Appointment Letter Is Now Mandatory — Format, Required Contents & Penalties

In one line: Since the OSH & Working Conditions Code, 2020 became operational on 21 November 2025, every Indian employer must issue a written appointment letter to every employee — permanent, fixed-term, contract, gig (where applicable) — on or before joining.

The Statutory Hook

Section 6, OSH Code, 2020:

“No employer of an establishment shall employ any worker in his establishment unless an appointment letter has been issued by the employer to the employee in such form and manner as may be prescribed by the Central Government.”

Section 6 sets out the broader statutory duties of an employer under the OSH Code — maintaining a safe, hazard-free work environment, providing free annual health examinations, proper disposal of toxic waste, and issuing formal appointment letters to all staff. The appointment letter obligation sits within this same section.

The Central Rules (notified 8 May 2026) specify 12 mandatory contents the letter must include.

The 12 Mandatory Clauses (Central Rules, Form A)

  1. Name, address, email of the employer (the legal entity, not a brand name)
  2. Name, photograph, date of birth, gender of the employee
  3. Aadhaar number (or UAN/ESIC number where applicable)
  4. Designation and category of work
  5. Date of joining
  6. Period of employment (if fixed-term)
  7. Wage rate and components — basic, DA, allowances (must satisfy 50% basic rule)
  8. Working hours and shift schedule
  9. Leave entitlement (annual, casual, sick)
  10. Notice period from either side
  11. Place of work (including remote/hybrid if applicable)
  12. Statutory contributions — PF UAN, ESIC IP number, NPS PRAN (if any)

Why Old “Offer Letters” Don’t Cut It

Many companies historically issued only an offer letter without a separate appointment letter. Under Section 6, the appointment letter is a statutory mandatory document — separate from the offer letter — and must contain all 12 prescribed elements.

✅ Best practice: combine into a single document titled “Appointment Letter” that satisfies both contractual and statutory requirements.

What If You Hired Someone Pre-Nov 2025?

The Code is silent on retroactive issuance, but state Labour Departments have clarified: re-issue an appointment letter to every existing employee within a reasonable period (most states have given 90–180 days). Many large employers completed bulk re-issuance via DigiLocker integrations during Q1–Q2 2026.

Penalties For Not Issuing

  • Section 96, OSH Code: Fine up to ₹50,000 per employee per offence
  • Repeat offence within 5 years: Up to ₹1,00,000 + 3 months imprisonment
  • Worker remedy: Direct complaint to Inspector-cum-Facilitator (Section 34) or Labour Court
  • Insurance angle: Some employer-side insurance claims may be repudiated without a valid appointment letter

Code-Compliant Appointment Letter — Key Elements

Your appointment letter must cover all 12 clauses above. Key points to note in drafting:

On wages (Clause 7): Basic Pay must be at least 50% of total remuneration per Section 2(y) of the Code on Wages. An appointment letter showing Basic below 50% of gross is non-compliant with the Wages Code in addition to being an incomplete appointment letter.

On working hours (Clause 8): Must specify that hours comply with Section 25 of the OSH Code — maximum 8 hours/day, 48 hours/week.

On leave (Clause 9): Must reflect the new thresholds — earned leave eligibility after 180 days worked (not 240), maximum 30-day carry-forward.

On place of work (Clause 11): Remote and hybrid arrangements must be explicitly stated — “Office: [address] / Remote: [city] / Hybrid: [X days WFO per week].” Ambiguity creates jurisdictional issues for dispute resolution.

On statutory contributions (Clause 12): PF UAN and ESIC IP number must be filled in before or at joining — not left blank “to be updated.”

Common Mistakes To Avoid

  1. ❌ Listing basic pay below 50% of total remuneration → triggers Section 2(y) restatement
  2. ❌ Using a brand name instead of the legal entity → letter may be deemed invalid
  3. ❌ Missing Aadhaar/UAN → blocks downstream EPFO/ESIC registration
  4. ❌ Not specifying place of work for remote/hybrid roles → ambiguity in jurisdiction
  5. ❌ Forgetting to issue to fixed-term and contract workers — explicitly covered under Section 6
  6. ❌ Issuing offer letter only without separate statutory appointment letter

What HR Must Do This Week

  1. Audit current appointment-letter template against the 12 mandatory clauses
  2. Re-issue to any employee hired before 21 November 2025 without one
  3. Enable digital signing + DigiLocker storage
  4. Update offer-letter SOP so appointment letter is auto-generated at offer acceptance
  5. Train HR Ops team on the new format requirements

Frequently Asked Questions

Can the appointment letter be in English only? Section 6(b) of the Central Rules requires it in English plus the language understood by the worker. Best practice: dual-language template (English + regional language).

Is digital signature acceptable? Yes — Aadhaar-based eSign or DSC under the IT Act, 2000 is valid.

For gig workers — same rules? Aggregators have a separate registration obligation under Section 113 of the Social Security Code (45-day window). The OSH appointment letter under Section 6 doesn’t apply to non-employee gig workers.

What if the employee refuses to sign? The employer’s obligation is to issue. Maintain proof of delivery (email + courier + acknowledgment). Refusal doesn’t void the letter.

Does this apply to contract labour too? Yes — the contractor must issue appointment letters to contract labour engaged. The principal employer is responsible for welfare facilities but the contractor holds the appointment letter obligation.

What if our CTC shows basic below 50% in the appointment letter? The appointment letter itself becomes evidence of non-compliance with the Code on Wages. Update the salary structure before issuing new appointment letters.
