1. Meaning

Employee continuity across subsidiaries refers to the legal and employment-law issues that arise when an employee moves, is transferred, deputed, seconded, or otherwise continues working from one company within a corporate group to another subsidiary, affiliate, associate, or group entity.

For example:

Company A Ltd. employs an employee. The employee is transferred to Company B Ltd., a subsidiary of Company A, without a complete break in service.

The central legal question is:

Does the employee's previous service with the first company continue to be recognized after moving to the subsidiary?

This becomes particularly important for:

• continuity of service;
• gratuity;
• provident fund;
• leave;
• bonus;
• retirement benefits;
• seniority;
• pension;
• notice period;
• retrenchment compensation;
• employee stock options;
• confidentiality;
• long-service benefits; and
• termination rights.

2. Corporate Group Does Not Automatically Mean One Employer

One of the most important principles is that a parent company and its subsidiary are ordinarily separate legal entities.

Even where:

• the same shareholders control both companies;
• the same directors manage them;
• they share offices;
• they use the same brand;
• employees are transferred between them; or
• one company owns the majority of the other,

each company may still be a separate employer.

Therefore, simply saying:

"Company B is a wholly owned subsidiary of Company A"

does not automatically establish continuity of employment.

The actual legal relationship must be examined.

3. Why Continuity Matters

Suppose an employee works:

• 7 years with Parent Company A; and
• 4 years with Subsidiary B.

If the employee's service is legally continuous, the employee may potentially have 11 years of recognized service for purposes where continuous service is relevant.

If the transfer is treated as a fresh employment relationship, the employee's service with Company B could potentially begin from year zero for certain benefits.

This distinction can have significant financial consequences.

4. Types of Movement Between Subsidiaries

A. Transfer

The employee is moved from one group company to another.

Example:

ABC Ltd. transfers an employee to ABC Technologies Pvt. Ltd.

The employee may retain:

• salary;
• designation;
• service history;
• benefits;
• seniority.

B. Secondment

The employee remains employed by the original company but works for another group entity.

For example:

Company A remains the legal employer, while the employee performs services for Company B for three years.

This is different from a permanent transfer.

C. Deputation

An employee may be temporarily placed with another entity while retaining the original employment relationship.

This is particularly common in:

• public-sector organizations;
• banking;
• insurance;
• government-controlled companies;
• large corporate groups.

D. Fresh Appointment

The employee resigns from Company A and enters into a completely new employment contract with Company B.

In such a case, continuity is more difficult to establish unless:

• the documents preserve previous service;
• applicable law recognizes it;
• the employer expressly agrees; or
• the transaction is legally structured as a transfer rather than termination and reappointment.

5. Contractual Continuity Clause

A well-drafted transfer agreement can state:

"The employee's service with the transferor company shall be treated as continuous service with the transferee company for all applicable employment benefits."

Such a clause can be extremely important.

It should specify whether continuity applies to:

• gratuity;
• leave;
• provident fund;
• pension;
• bonus;
• seniority;
• notice period;
• retirement age;
• long-service benefits; and
• other contractual benefits.

6. Transfer of Employment and Employee Consent

Whether an employer can transfer an employee from one legal entity to another depends on:

• employment contract;
• service rules;
• standing orders;
• applicable labour legislation;
• nature of the transfer;
• employee consent;
• whether employment is terminated and recreated; and
• whether the transfer affects existing rights.

A company should not assume that a clause permitting transfer between departments automatically permits transfer to a different legal employer.

7. Continuity of Service Under Indian Labour Law

The concept of continuous service is particularly important under Indian labour legislation.

For example, the Industrial Disputes Act, 1947 contains provisions concerning continuous service, including Section 25B.

Similarly, the Payment of Gratuity Act, 1972 recognizes continuous service for determining gratuity entitlement.

Consequently, an employee's movement between group companies can affect statutory benefits if continuity is not properly preserved.

8. Gratuity and Inter-Company Transfers

Gratuity is one of the most important areas.

Under the Payment of Gratuity Act, 1972, an employee satisfying the statutory requirements can become entitled to gratuity based on qualifying continuous service.

Suppose:

• Company A: 8 years;
• Company B: 5 years.

If the transfer is structured so that service remains continuous, the employee may have 13 years of recognized service for gratuity purposes.

If Company B treats the employee as a new employee without recognizing earlier service, a dispute can arise.

The documentation surrounding the transfer therefore becomes extremely important.

9. Provident Fund Continuity

Employees moving between group companies may also have issues involving:

• EPF membership;
• UAN;
• employer contributions;
• pension contributions;
• transfer of accumulated balance; and
• continuity of records.

A change in employer does not necessarily mean the employee loses accumulated provident-fund benefits.

However, administrative transfer and legal continuity of employment are distinct questions.

10. Leave and Other Benefits

A transfer agreement should clarify whether previous service counts for:

• earned leave;
• privilege leave;
• sick leave;
• leave encashment;
• long-service awards;
• medical benefits;
• retirement benefits;
• bonus;
• insurance;
• employee stock plans.

Without clear documentation, employees and group companies may later disagree over whether previous service should be recognized.

11. Seniority

Seniority becomes particularly important in:

• public-sector employment;
• regulated industries;
• unionized workplaces;
• organizations with structured promotion systems.

A transfer from one subsidiary to another can raise questions such as:

Does the employee retain the seniority accumulated in Company A?

The answer depends upon the relevant service rules and contractual arrangements.

12. Corporate Veil and Common Employer

Indian courts generally recognize the separate legal identity of companies.

However, in appropriate cases, courts may examine whether separate corporate entities are being used merely as a device to defeat legal rights.

Relevant factors can include:

• common management;
• financial integration;
• control;
• common business;
• common employees;
• transfer of assets;
• interdependence; and
• the actual substance of the relationship.

The mere existence of a corporate group, however, is not enough by itself.

13. Important Case Laws

Case 1: Salomon v. A. Salomon & Co. Ltd.

Citation: [1897] AC 22

Although this is an English House of Lords decision, it is a foundational authority on corporate personality and is highly relevant to understanding subsidiary relationships.

Principle

A company has a legal personality separate from its shareholders and related persons.

Relevance to employee continuity

A parent company and its subsidiary are normally separate legal persons.

Therefore:

Parent company + subsidiary ≠ automatically one employer.

If an employee moves from one to another, the legal consequences depend on the employment arrangement and applicable law.

Case 2: Vodafone International Holdings BV v. Union of India

Citation: (2012) 6 SCC 613

Facts

The case concerned corporate structures and the relationship between different entities in a corporate group.

Supreme Court's approach

The Supreme Court recognized the importance of respecting separate corporate personality while examining the substance of corporate arrangements.

Relevance

A subsidiary should ordinarily be treated as a separate legal entity.

Therefore, employees cannot automatically assume that employment with a parent company is legally identical to employment with its subsidiary.

Principle

Corporate structure and separate legal personality matter when determining rights and obligations.

Case 3: State of U.P. v. Renusagar Power Co.

Citation: (1988) 4 SCC 59

Facts

The case concerned the relationship between a parent company and its subsidiary and whether the separate corporate personality should be disregarded in the circumstances.

Supreme Court's decision

The Court examined the close relationship between the entities and considered circumstances in which the corporate veil may be lifted.

Relevance

For employee continuity disputes, a court may examine the actual relationship between entities in appropriate circumstances.

However, the case should not be interpreted as meaning that every subsidiary automatically becomes the same employer as its parent.

Principle

The corporate veil may be lifted in appropriate circumstances, but separate corporate personality remains the general rule.

Case 4: Workmen of the Food Corporation of India v. Food Corporation of India

Citation: (1985) 2 SCC 136

Relevance

The Supreme Court considered employment-related questions involving workers, service conditions, and the relationship between employment arrangements and statutory labour protections.

The case illustrates that courts examine the substance of the employment relationship, rather than merely relying on labels.

Application to subsidiary transfers

Calling an arrangement:

"transfer,"
"deputation," or
"fresh appointment"

does not by itself determine the legal consequences.

The underlying documents and actual employment relationship matter.

Principle

The substance of an employment arrangement is important when determining employee rights.

Case 5: Balwant Rai Saluja v. Air India Ltd.

Citation: (2014) 9 SCC 407

Facts

The dispute involved employees working in an establishment through a contractor and questions concerning the relationship between the principal establishment and workers.

Supreme Court's decision

The Court carefully examined the distinction between formal legal relationships and actual control/supervision.

It cautioned against automatically treating workers of one entity as employees of another merely because of operational control or a close relationship.

Relevance

This is highly useful when considering group companies.

For example, the fact that:

• Parent Company A supervises an employee;
• Company B pays certain expenses; and
• the employee works in the parent company's office

does not automatically establish that A and B are the same employer.

Principle

Actual control is relevant, but it does not automatically eliminate separate legal relationships.

Case 6: Tata Engineering and Locomotive Co. Ltd. v. State of Bihar

Citation: (1964) 6 SCR 885

Relevance

The Supreme Court emphasized the separate legal identity of companies and the circumstances in which related corporate entities should or should not be treated separately.

Application

For employee continuity, a group company should not automatically be treated as the same employer merely because the companies have:

• common ownership;
• common management;
• common branding; or
• financial relationships.

Principle

Separate corporate personality must ordinarily be respected unless circumstances justify otherwise.

Case 7: New Horizons Ltd. v. Union of India

Citation: (1995) 1 SCC 478

Facts

The Supreme Court considered a corporate consortium and the relationship among participating entities.

Relevance

The case demonstrates that courts may examine the substance and commercial reality of relationships among corporate entities.

For employee-transfer arrangements, this supports careful examination of:

• who employs the employee;
• who pays salary;
• who controls employment;
• who bears employment liabilities; and
• what the contractual documents say.

Principle

Corporate relationships should be analyzed by considering the actual legal and commercial arrangement rather than assumptions based solely on corporate affiliation.

Case 8: Balmer Lawrie & Co. Ltd. v. Partha Sarathi Sen Roy

Citation: (2013) 8 SCC 345

Relevance

The Supreme Court considered employment conditions and the legal consequences of service arrangements.

The case reinforces the importance of examining applicable service rules and contractual rights rather than treating employment arrangements mechanically.

Principle

Employee rights depend upon the governing service framework and cannot be determined solely by organizational labels.

14. When Continuity Is More Likely to Be Recognized

Continuity becomes stronger where:

• the transfer document expressly preserves service;
• there is no break in employment;
• the employee continues performing substantially the same work;
• the new entity accepts prior service;
• the group companies agree to recognize previous service;
• statutory benefits are transferred;
• salary and benefits continue substantially unchanged; and
• the transaction is structured as a genuine transfer rather than resignation and fresh appointment.

15. When Continuity Is Less Certain

Continuity may be more difficult to establish where:

• the employee resigns from Company A;
• Company A accepts the resignation;
• Company B issues a completely new appointment letter;
• prior service is expressly excluded;
• all benefits are settled by Company A;
• a new probationary period begins; and
• the employee has a separate employment contract with Company B.

Even then, statutory rights and specific contractual arrangements must be separately examined.

16. Transfer Agreement — Important Clauses

A transfer agreement should ideally specify:

1. Effective date

"The transfer shall take effect from 1 October 2026."

2. Continuity

"The employee's service from 1 April 2018 shall be treated as continuous for the purposes specified herein."

3. Gratuity

Specify whether prior service will be recognized for gratuity purposes.

4. Leave

State whether accumulated leave will:

• transfer;
• be encashed; or
• remain with the original employer.

5. Provident fund

Specify how PF records and contributions will be handled.

6. Seniority

State whether prior seniority will be retained.

7. Compensation

Specify whether:

• salary;
• bonus;
• allowances;
• insurance; and
• other benefits

continue unchanged.

8. Liabilities

Specify which entity is responsible for obligations arising before and after the transfer.

17. Employee Continuity in Mergers and Acquisitions

Continuity issues become especially important during:

• mergers;
• demergers;
• acquisitions;
• business transfers;
• corporate restructuring.

Suppose:

Company A acquires the business of Company B and employees are transferred to Company A.

The transaction documents may provide that employees' previous service is recognized.

The treatment of employee liabilities should be expressly addressed.

This is particularly important for:

• gratuity;
• leave;
• PF;
• bonus;
• pending litigation;
• disciplinary proceedings; and
• employment claims.

18. Continuity and Termination

Suppose:

Company A transfers an employee to Company B and Company B later terminates the employee.

The employee may argue that the entire period from the original joining date should be considered for calculating statutory or contractual entitlements.

The employer may argue that Company B employment began on the transfer date.

The answer will depend upon:

• transfer documents;
• statutory provisions;
• continuity clauses;
• treatment of benefits;
• whether employment was actually terminated;
• applicable standing orders; and
• relevant judicial principles.

19. Practical Example

Facts

An employee joined Parent Company A in 2016.

In 2021, the employee moved to Subsidiary B.

The transfer letter stated:

"All previous service shall be recognized for purposes of continuity of service."

The employee leaves in 2026.

Position

The employee has potentially completed 10 years of recognized service, assuming the relevant statutory and contractual requirements are satisfied.

The employer cannot simply argue:

"You joined Subsidiary B in 2021, so you have only five years."

The contractual continuity clause becomes significant.

20. Another Example — Fresh Appointment

Employee:

• Company A: 2016–2021
• Resignation: 2021
• Company B: new appointment from 2021
• Separate contract
• Previous service expressly not recognized

Here, continuity is much less straightforward.

The employee may still retain benefits already accrued under applicable law, but whether Company B must count the earlier period for future entitlements will depend on the applicable statutory and contractual framework.

21. Key Legal Principles

22. Best Practices for Employers

Before moving an employee between subsidiaries, employers should:

1. Identify the existing legal employer.
2. Review the employment agreement.
3. Determine whether transfer is contractually permitted.
4. Decide whether the move is a transfer, secondment, deputation, or fresh appointment.
5. Clearly document continuity.
6. Address gratuity.
7. Address PF.
8. Address leave.
9. Address seniority.
10. Address bonus and incentives.
11. Address stock options.
12. Address pending disciplinary matters.
13. Allocate pre-transfer and post-transfer liabilities.
14. Give the employee a written transfer document.
15. Maintain consistent records across the group entities.

23. Best Practices for Employees

Employees moving between subsidiaries should obtain written clarification concerning:

• original joining date;
• recognized service date;
• gratuity;
• leave balance;
• PF;
• pension;
• seniority;
• bonus;
• stock options;
• notice period;
• retirement age;
• insurance;
• pending claims; and
• treatment of service upon future termination.

An employee should not rely solely on an oral assurance such as:

"Don't worry, your service will continue."

The continuity arrangement should preferably appear in the written employment/transfer documentation.

24. Conclusion

Employee continuity across subsidiaries is not automatic merely because companies belong to the same corporate group. The parent company and subsidiary are ordinarily separate legal entities, and the question of continuity must be determined by examining the employment contract, transfer documents, applicable labour legislation, and the actual nature of the employment relationship.

The important cases—including Salomon v. Salomon, Vodafone International Holdings v. Union of India, State of U.P. v. Renusagar Power Co., Balwant Rai Saluja v. Air India, Tata Engineering & Locomotive Co. v. State of Bihar, and New Horizons Ltd. v. Union of India—illustrate the importance of separate corporate personality, substance of the employment relationship, and the circumstances in which corporate separateness may or may not be disregarded.

For practical purposes, the safest approach is to document expressly:

"The employee's service with the transferor entity shall be treated as continuous with the transferee entity for [specified statutory and contractual benefits]."

Such clarity reduces disputes concerning gratuity, leave, provident fund, seniority, termination benefits, and other long-service entitlements.
