1. Introduction

Pay adjustments for retention equity refer to changes in employee compensation made to retain valuable employees, correct unfair pay differences, improve internal pay fairness, and maintain competitiveness in the labour market.

Organisations often face situations where experienced employees receive lower salaries than newly recruited employees performing similar work. This may happen because of market salary increases, hiring shortages, changes in job responsibilities, promotion delays, or inconsistent salary-setting practices. Such differences can create dissatisfaction, reduce employee motivation, and increase turnover.

Retention-related pay adjustments may include salary increases, market corrections, retention bonuses, equity-based compensation, revised allowances, and long-term incentive arrangements.

However, employers must balance employee retention with equal-pay requirements, employment contracts, non-discrimination legislation, budgetary limits, and transparent compensation practices.

The central legal question is: Can an employer adjust compensation to retain particular employees without creating unlawful discrimination or unjustified pay disparities among other employees?

The answer depends on the applicable jurisdiction, the reason for the pay difference, the terms of employment, and the legal protections available to affected employees.

2. Meaning of Pay Adjustments for Retention Equity

Pay adjustments for retention equity involve changes to compensation intended to ensure that employees are paid fairly while helping an organisation retain essential skills and experience.

The term has two related meanings:

Retention pay adjustments: Salary increases, bonuses, or other financial incentives offered to persuade employees to remain with the organisation.

Pay equity adjustments: Corrections to unjustified differences in compensation between employees performing equal, substantially similar, or comparable work, depending on the governing law.

These objectives may overlap. For example, an employer may increase the salary of a highly experienced employee because competing employers are offering higher salaries, while also reviewing whether employees performing equivalent work are being paid fairly.

The expression retention equity can also refer to equity-based awards, such as restricted stock units or stock options, granted to encourage employees to remain with a company. The legal treatment of these awards differs from that of ordinary salary adjustments.

3. Common Types of Retention-Related Pay Adjustments

A. Market salary adjustments

An employer increases an employee's salary to match prevailing market rates for a particular role or skill set.

For example, a software specialist earning ₹8 lakh annually may receive a salary correction when comparable positions begin paying ₹10 lakh because of increased demand.

B. Internal pay-equity corrections

An organisation reviews salaries across employees performing comparable work and corrects unjustified differences.

Such corrections may be necessary where historical salary decisions, inconsistent negotiations, or biased compensation practices have produced unfair disparities.

C. Retention bonuses

A retention bonus is a one-time or staged payment offered in return for remaining employed for a specified period or completing a particular project.

The agreement should clearly explain the payment amount, eligibility requirements, payment date, repayment conditions, and consequences of resignation or termination.

D. Long-term incentives

Employers may offer stock options, restricted stock units, or other long-term incentives to encourage employees to remain with the organisation.

These arrangements may involve vesting periods, performance conditions, forfeiture provisions, and securities-law requirements.

E. Promotion and responsibility adjustments

Employees may receive salary increases when they take on additional responsibilities, manage larger teams, acquire specialist skills, or move into more senior positions.

F. Salary compression corrections

Salary compression occurs when newer employees earn nearly as much as, or more than, experienced employees performing comparable work. Employers may adjust salaries to recognise experience, responsibilities, qualifications, and relevant performance differences.

4. Legal Framework in India

A. Code on Wages, 2019

Section 3 of the Code on Wages, 2019 prohibits gender-based discrimination in wages for the same work or work of a similar nature by the same employer. It also prohibits reducing an employee's wage rate merely to achieve compliance with the equal-wage requirement. The application of this provision must be assessed with the Code's commencement and applicable rules.

This provision is important when an employer grants retention increases selectively. A salary difference is not automatically unlawful merely because two employees earn different amounts. However, an employer should be able to explain differences that may be challenged as gender-based discrimination.

B. Constitution of India

Article 14 guarantees equality before the law, while Article 16 addresses equality of opportunity in public employment. Article 39(d), a Directive Principle of State Policy, calls for equal pay for equal work for both men and women.

These principles are particularly relevant to government employment and public-sector pay disputes. Their application to a particular claim depends on the employer's status and the legal basis of the dispute.

C. Employment contracts and service rules

Where an employer promises a salary increase, retention bonus, or incentive under an employment contract or written compensation plan, the terms of that arrangement may determine whether payment is due.

Relevant questions include whether the award is discretionary or contractual, whether eligibility conditions were fulfilled, and whether the employer complied with applicable service rules.

D. Non-discrimination and fair compensation

Retention decisions should not be used to conceal discriminatory pay practices. Employers should document objective reasons for salary differences, such as market conditions, scarce skills, additional responsibilities, performance, or relevant experience.

An employer may have a legitimate business reason to retain a specialist employee, but that reason does not automatically excuse unlawful discrimination.

5. Important Case Laws on Pay Adjustments and Pay Equity

The following cases establish important principles concerning equal pay, wage discrimination, compensation structures, and fair treatment. Not every case concerns retention bonuses directly; several provide principles that can be applied to retention-related pay disputes.

Case 1: Randhir Singh v. Union of India (1982)

Court: Supreme Court of India.

Legal issue: Equal pay for equal work in public employment.

The petitioner, a driver in the Delhi Police, claimed that his pay should be equivalent to that of drivers performing comparable work in other government departments.

The Supreme Court recognised that equal pay for equal work is a constitutional goal reflected in Articles 14, 16, and 39(d). It explained that the principle may be enforced through constitutional equality provisions in appropriate circumstances.

Legal principle: Employees performing comparable work may challenge unjustified pay differences, particularly where the disparity is inconsistent with constitutional equality requirements.

Relevance to retention equity: A public employer should not rely solely on administrative convenience when setting different pay scales for employees performing comparable duties. Retention adjustments should be considered alongside legitimate job-related differences and applicable pay rules.

Case 2: Mackinnon Mackenzie & Co. Ltd. v. Audrey D'Costa (1987)

Court: Supreme Court of India.

Legal issue: Equal remuneration for women and men performing comparable work.

The case concerned female stenographers who received lower wages than male stenographers. The employer argued that the jobs were different, but the Court examined the actual duties and responsibilities performed.

The Supreme Court emphasised that the nature of the work, rather than merely the job title or the employer's classification, is important when determining whether work is the same or similar.

Legal principle: Employers cannot justify unequal remuneration simply by assigning different labels to substantially similar jobs where the relevant legal requirements for equal pay are met.

Relevance to retention equity: If an organisation grants larger salary adjustments to employees in one gender group while employees of another gender perform the same or similar work, it should review the criteria and evidence supporting the difference.

Case 3: State of Punjab v. Jagjit Singh (2016)

Court: Supreme Court of India.

Legal issue: Equal pay for temporary employees performing the same duties as regular employees.

The case involved temporary and contractual employees who claimed wages equivalent to those of regular employees performing similar duties.

The Supreme Court recognised that temporary employees may be entitled to the minimum of the regular pay scale where the relevant conditions are satisfied. The decision rejected the assumption that temporary status alone always justifies substantially lower remuneration for comparable work.

Legal principle: Employment classification is not necessarily sufficient to justify a pay difference when employees perform the same duties and satisfy the applicable legal requirements.

Relevance to retention equity: Employers should assess whether differences in employment status, experience, responsibility, and compensation structure genuinely justify different pay. A retention increase should not become a substitute for reviewing potentially unlawful disparities affecting temporary or contractual employees.

Case 4: Air India v. Nergesh Meerza (1981)

Court: Supreme Court of India.

Legal issue: Employment conditions and discriminatory service rules affecting air hostesses.

The case challenged aspects of Air India's service regulations concerning air hostesses, including provisions relating to retirement, pregnancy, and other employment conditions.

The Supreme Court examined the validity of employment rules under constitutional equality principles. Although the judgment did not establish a general right to retention-related pay increases, it is relevant to the broader requirement that employment conditions be legally defensible.

Legal principle: Employment rules and compensation-related conditions in public employment may be examined for arbitrariness and constitutional validity.

Relevance to retention equity: Where public-sector retention benefits or compensation rules distinguish between groups of employees, the criteria should have a defensible basis and comply with applicable equality requirements.

Case 5: Bhagwan Dass v. State of Haryana (1987)

Court: Supreme Court of India.

Legal issue: Equal remuneration for employees performing comparable work.

The case concerned employees seeking equal treatment in remuneration. The Supreme Court considered the importance of the principle of equal pay for equal work in the context of the employees' actual duties and applicable service arrangements.

Legal principle: Where the relevant work is comparable, differences in remuneration require examination of the actual duties, responsibilities, and governing employment conditions rather than reliance on labels alone.

Relevance to retention equity: An employer reviewing retention-related salary differences should compare the actual work performed, the level of responsibility, and the legitimate reasons for any pay disparity.

Case 6: Corning Glass Works v. Brennan (1974)

Court: Supreme Court of the United States.

Legal issue: Unequal wages for men and women performing equal work.

Female employees performing inspection work during the day received lower base wages than male employees who performed comparable inspection work at night. The employer relied on its wage-setting practices and differences in working arrangements.

The Supreme Court found a violation of the Equal Pay Act for the relevant period and examined the statutory requirements for permissible wage differences.

Legal principle: Differences in compensation must satisfy the applicable statutory requirements. An employer cannot automatically justify a wage disparity by relying on historical practices or a particular compensation arrangement.

Relevance to retention equity: Historical salary decisions should be reviewed carefully. An employer should not perpetuate an unjustified pay gap simply because it has existed for years or because an employee's salary was initially negotiated at a lower level.

Case 7: County of Washington v. Gunther (1981)

Court: Supreme Court of the United States.

Legal issue: The scope of legal protection against sex-based wage discrimination.

Female prison guards alleged that their compensation was lower than that of male guards and that the difference was partly attributable to sex discrimination. Their claim included an argument based on the employer's own job evaluations and wage-setting practices.

The Supreme Court held that Title VII's prohibition on sex-based wage discrimination is not confined exclusively to claims involving equal work under the Equal Pay Act.

Legal principle: A wage-discrimination claim under Title VII may succeed in circumstances that do not meet the Equal Pay Act's narrower equal-work test, subject to the applicable legal requirements and defences.

Relevance to retention equity: An employer should examine whether a retention-pay scheme has a discriminatory effect or is based on discriminatory criteria. Merely assigning employees to different job categories does not necessarily resolve every discrimination claim.

Case 8: Ledbetter v. Goodyear Tire & Rubber Co. (2007)

Court: Supreme Court of the United States.

Legal issue: Time limits for bringing compensation-discrimination claims.

Lilly Ledbetter alleged that she had received lower pay than male colleagues because of sex discrimination over an extended period. The Supreme Court interpreted the applicable statutory filing deadline in relation to the challenged compensation decisions.

Congress subsequently enacted the Lilly Ledbetter Fair Pay Act of 2009, which changed the relevant rules for compensation-discrimination claims under covered federal laws.

Legal principle: Compensation disputes may involve complex limitation periods, and the legal consequences of a continuing pay disparity depend on the governing statute and subsequent legislation.

Relevance to retention equity: Employers should review compensation systems periodically, document salary decisions, and address unjustified disparities promptly. Employees should also seek advice about applicable deadlines rather than assume that an old pay decision can always be challenged at any time.

6. Legal Principles Emerging from the Case Laws

The cases above suggest several principles for employers considering retention-related compensation adjustments.

Equal-pay obligations remain applicable. Retention objectives do not exempt employers from applicable anti-discrimination and equal-pay laws.

Actual duties matter. Job titles alone may not establish that two roles are materially different.

Objective justification is important. Market scarcity, performance, experience, responsibilities, and measurable business needs may support pay differences where the law permits those factors.

Historical practices are not conclusive. An established salary structure may still require correction if it produces unlawful disparities.

Employment status must be considered carefully. Differences between temporary, contractual, and permanent employees must be evaluated under the applicable law and circumstances.

Written records reduce disputes. Documented compensation criteria help demonstrate how retention awards and salary corrections were determined.

Legal deadlines matter. Employees and employers should identify applicable limitation periods and procedural requirements promptly.

7. Employer Responsibilities When Making Retention Pay Adjustments

A. Conduct a compensation audit

Employers should review salary levels across comparable roles, departments, locations, and employment categories. The audit should identify unexplained differences and determine whether corrective action is required.

B. Establish objective eligibility criteria

A retention-pay scheme should specify the factors used to select eligible employees. Relevant considerations may include:

Scarcity of particular skills.

Documented recruitment or replacement difficulties.

Critical project responsibilities.

Experience and specialist qualifications.

Performance and measurable contribution.

Internal pay-equity requirements.

Criteria should be applied consistently and should not operate as a pretext for unlawful discrimination.

C. Distinguish recurring salary from one-time bonuses

A permanent salary adjustment may affect future salary increases, retirement-related calculations, and other benefits where the relevant rules so provide.

A one-time retention bonus may be structured differently. Its payment conditions, tax treatment, and any repayment provision should be clearly documented and legally reviewed.

D. Explain the compensation decision

Managers should be able to explain why a particular employee qualifies for an adjustment and why comparable employees may receive different amounts. Confidentiality should be respected, but it should not be used to conceal unlawful discrimination.

E. Review contractual and regulatory requirements

Before granting an adjustment, employers should examine employment contracts, collective agreements, standing orders, applicable wage legislation, internal compensation policies, and any relevant sector-specific rules.

8. Employee Rights and Possible Remedies

An employee who believes that retention-related pay decisions are unfair may consider the following steps:

Request clarification of the applicable salary or bonus criteria.

Review the employment contract and compensation policy.

Preserve salary slips, offer letters, performance records, and written communications about the adjustment.

Raise a grievance through the organisation's HR or grievance procedure.

Seek assistance from the appropriate labour authority or other competent body where applicable.

Obtain legal advice about discrimination claims, contractual payment claims, or other available remedies.

A lower salary or failure to receive a retention bonus does not, by itself, prove unlawful discrimination. The employee must establish the relevant legal basis for the claim, and the employer may have legitimate reasons for differing compensation.

9. Practical Example

Suppose a company employs three legal researchers performing comparable work.

The employer explains that Employee A has specialist expertise that is difficult to replace and is responsible for a critical project.

That explanation may support a legitimate retention adjustment if the facts substantiate it and the decision complies with applicable law. However, if the difference is actually based on gender or another legally protected characteristic, the retention rationale would not automatically make it lawful.

A proper review should examine the employees' duties, experience, performance, market rates, and the objective criteria used to determine the awards.

10. Conclusion

Pay adjustments for retention equity help employers retain valuable employees, correct salary compression, and maintain competitive compensation structures. However, retention objectives must be balanced with equal-pay obligations, anti-discrimination principles, contractual commitments, and transparent decision-making.

The decisions in Randhir Singh, Mackinnon Mackenzie, Jagjit Singh, Air India, Bhagwan Dass, Corning Glass Works, County of Washington, and Ledbetter illustrate different aspects of equal remuneration, compensation fairness, and wage-discrimination law. Their legal significance varies by jurisdiction, and the foreign decisions are persuasive illustrations rather than binding precedents in India.

Ultimately, a defensible retention-pay system should be based on legitimate business needs, objective criteria, documented decisions, regular compensation audits, and compliance with applicable law. Retaining employees is a valid business objective, but it should not be achieved by creating or perpetuating unlawful pay disparities.
