Appointment Letters Are Now Mandatory for Every Employee
The OSH Code makes a written appointment letter mandatory for every employee in India. Here is what it must contain and how employers should roll it out.
Under the Occupational Safety, Health and Working Conditions Code, every employer must issue a written appointment letter to every employee, and this now applies to existing staff, not just new hires.
Key facts at a glance
- The OSH Code mandates a written appointment letter for every employee, replacing informal or verbal engagement arrangements.
- The requirement applies to existing employees as well as new hires, meaning employers need to close gaps for staff who never received one.
- Appointment letters must cover key particulars such as designation, category of work, and wages.
- The requirement is understood to extend to fixed-term and other categories of workers, not only regular employees.
- Electronic issuance of appointment letters is generally expected to satisfy the requirement, subject to state-specific format rules.
- The OSH Code is in force nationally from 21 November 2025, with practical enforcement depending on state rule notification.
Why this matters beyond a paperwork exercise
Historically, many small and mid-sized Indian businesses hired employees on the basis of a verbal offer or a brief email, without a formal appointment letter spelling out terms of employment. This created ambiguity around designation, wage structure, and working conditions, which surfaced most painfully during disputes, exits, or audits, when there was no clear documentary record to refer back to.
The OSH Code closes this gap by making a written appointment letter a legal requirement rather than a best practice, which changes the risk calculus for employers who have relied on informal engagement.
What an appointment letter needs to cover
While exact formatting requirements will be shaped by state rules, an appointment letter under the OSH Code framework is generally expected to document the employee's designation and role, the category of work they are engaged for, wage details, and other prescribed particulars relevant to the terms of employment. The goal is to give both employer and employee a clear, shared reference point for the employment relationship from day one.
Comparing informal engagement with the new requirement
| Aspect | Informal engagement (pre-Code practice) | OSH Code requirement |
|---|---|---|
| Documentation | Verbal offer or brief email, often undocumented | Written appointment letter mandatory |
| Coverage | Often limited to certain roles or seniority | Every employee, across categories |
| Content | Inconsistent, employer's discretion | Designation, category of work, wages, prescribed particulars |
| Existing staff | Frequently left without formal letters | Expected to be brought up to date |
| Dispute resolution | Weak documentary evidence for either side | Clear documented terms as reference |
Closing the gap for existing employees
The most immediate task for HR teams is auditing the current workforce to identify who does not have a proper appointment letter on file. This is often a larger group than expected, particularly for employees who joined through informal channels, internal transfers, or role changes that were never formally documented. Once identified, employers should issue updated appointment letters covering current designation and terms, even for long-tenured staff.
Handling role or designation changes since hiring
For employees whose role or designation has changed materially since they joined, the appointment letter exercise is also a good opportunity to formally document the current position, rather than relying on an outdated original offer letter that no longer reflects reality.
Digital issuance and record-keeping
Given the broader push toward electronic compliance filing under the Labour Codes, digitally issued and acknowledged appointment letters are expected to be acceptable, provided the employer can retrieve and produce them when required. Employers should still confirm any state-specific format or retention requirements as rules are finalised.
What HR teams should do now
Run a workforce-wide audit to identify employees without a current, written appointment letter. Standardise a template that covers designation, category of work, wages and other required particulars, and roll it out systematically rather than piecemeal. Build appointment letter issuance into the onboarding checklist for every future hire so this never becomes a backlog again.

Frequently Asked Questions
- Is a written appointment letter now legally required for every employee?
- Yes, the Occupational Safety, Health and Working Conditions Code requires every employer to issue a written appointment letter to every employee, including those who were hired before the requirement came into effect.
- What should an appointment letter include under the OSH Code?
- An appointment letter should typically cover the employee's designation, category of work, wages, and other prescribed particulars, so it functions as clear documented evidence of the terms of employment rather than an informal offer.
- Do existing employees need a new appointment letter, or only new hires?
- The requirement is understood to apply to the workforce broadly, meaning employers should issue appointment letters to existing employees who do not already have one, not just to employees hired after the Codes came into force.
- What happens if an employer does not issue appointment letters?
- Failure to issue appointment letters exposes an employer to compliance risk under the OSH Code once the relevant state rules are enforced, and it also weakens the employer's position in any dispute over employment terms, since there is no documented record.
- Does this apply to contract workers and fixed-term employees too?
- Yes, the requirement for documented terms of engagement is understood to extend to fixed-term and other categories of workers, not just employees on regular, open-ended contracts, though the specific documentation may differ by category.
- Can an appointment letter be issued digitally or must it be on paper?
- The Codes generally support electronic documentation and filing, so a digitally issued and acknowledged appointment letter is expected to satisfy the requirement, provided it is properly recorded and retrievable, but employers should confirm format requirements under their state's specific rules.
- Is this requirement already being enforced?
- The OSH Code is nationally in force from 21 November 2025, but enforcement in practice depends on your state notifying its own rules, so employers should check their state's status while treating appointment letter issuance as good practice regardless.
