Appointment Letters: What HR Teams Should Include From Day One

An appointment letter should state, from day one, who the employee is, what job they are being hired for, on what type of employment, from what date, at what pay, with which social security benefits and on which key terms. In India it is no longer just good practice: the Occupational Safety, Health and Working Conditions Code, 2020 (OSH Code) requires every employer to issue an appointment letter to every employee, and the central rules set out the particulars it must contain. Existing employees who had no letter when the Code commenced on 21 November 2025 were to be given one within three months.

This guide covers the statutory particulars, the clauses most organizations add, how the letter differs from an offer letter, the mistakes that cause trouble later, and how to keep letters consistent as hiring grows.

Is an appointment letter mandatory in India?

Yes. Section 6(1)(f) of the OSH Code makes it a duty of every employer to issue a letter of appointment to every employee on appointment, with the information and in the form prescribed by the appropriate government. The Occupational Safety, Health and Working Conditions (Central) Rules, 2026, notified on 8 May 2026, go further: no employee shall be employed in an establishment unless an appointment letter has been issued in the prescribed format. The Ministry of Labour and Employment’s employer handbook lists “issue appointment letter to every new recruit” as an event-based compliance item.

Two practical points follow. First, the duty covers every employee, not only managers or permanent staff. Second, labour is a concurrent subject, so where the state government is the appropriate government, the state’s OSH rules and form apply. Check your state’s rules for the exact format; the central format below is a good baseline because state formats cover the same ground.

What the statutory format requires

Rule 6 of the OSH (Central) Rules, 2026 sets out these particulars:

Particular	Practical note
Name of employee	As on identity documents
Date of birth	Supports age-linked duties such as health examinations
Father’s or mother’s name	Either is accepted
Aadhaar number	Only after obtaining the employee’s consent
Labour Identification Number of the establishment	Your establishment’s identifier
Universal Account Number and/or ESI insurance number	If available at the time of issue
Designation	Should match your internal grade structure
Type of employment	Regular, fixed-term or contractual
Category of skill	For example unskilled, semi-skilled, skilled or highly skilled
Date of joining	The actual start date
Wages: basic pay and dearness allowance	State the wage components clearly
Other allowances, including accommodation	Whichever apply
Applicability of EPFO and ESIC benefits	Say whether each scheme applies to this employee
Broad nature of duties	A short summary, not the full job description
Maternity benefits under the Code on Social Security, 2020	For women employees
Any other information	Your contractual terms can sit here or in an annexure

The letter is signed by the employer, and a digital signature is allowed. Because the format asks for Aadhaar only with consent, handle that field as personal data: collect it with a clear purpose, store it securely and limit who can see it.

Clauses most employers add

The statutory particulars are the minimum. A complete appointment letter usually adds the terms that prevent disputes later:

• Probation: length, how performance will be reviewed, and what happens at the end, including how confirmation will be communicated. See when to issue a confirmation letter after probation.
• Working hours and place of work: normal hours, shift patterns, remote or hybrid arrangements and whether transfers are possible.
• Leave: a summary with a reference to the leave policy.
• Notice period and separation: notice on each side, and a line that dues are settled as required by law on exit.
• Confidentiality and intellectual property: what the employee must protect and who owns work created on the job.
• Policies by reference: code of conduct, anti-harassment (POSH) policy, IT use, data protection.
• Fixed-term specifics: end date, and that fixed-term employees get the same benefits as permanent staff doing the same work, with gratuity after one year of continuous service.
• Acceptance: a space for the employee to sign and date, and a request to return a copy.

Keep pay detail readable. Summarize the components in the letter and attach a salary annexure that shows the monthly and annual figures. Under the Labour Codes, basic pay plus dearness allowance should be at least half of total remuneration, or the excess of excluded allowances is treated as wages; check your structure before it goes into hundreds of letters.

Offer letter, appointment letter and contract: what each does

Document	Purpose	When
Offer letter	Proposes the role and headline pay; often conditional on checks	Before acceptance
Appointment letter	Statutory record of appointment with the prescribed particulars and key terms	On appointment, before or at the start of work
Employment contract	Detailed terms (restrictive covenants, IP, specific obligations)	Often signed with or as part of the appointment letter
Joining report or joining letter	Internal record that the employee has joined on a date	On the first day; optional

Many employers combine the appointment letter and contract into one document. That works, provided every statutory particular is present. Our guides to the key elements of an offer letter and employment contract clauses cover the other two documents.

Example: a short appointment letter outline

Example: a hypothetical outline for a regular, skilled role. Adapt it to your state’s form and your policies.

1. Company letterhead, Labour Identification Number, date and reference number.
2. Employee details: name, date of birth, parent’s name, Aadhaar (with consent), UAN or ESI number if available.
3. Appointment: designation, department, reporting manager, type of employment, category of skill, date of joining, place of work.
4. Wages: basic pay and dearness allowance, other allowances, with the full breakdown in Annexure A.
5. Social security: whether EPF and ESIC apply; for women employees, maternity benefit entitlement.
6. Duties: three or four lines summarizing the role, with the job description attached.
7. Terms: probation, hours, leave, notice, confidentiality, policies by reference.
8. Signature of the employer (physical or digital) and the employee’s acceptance with date.

Common appointment letter mistakes

• No letter for some groups. Contract, fixed-term and support staff are often missed. The duty covers every employee.
• Letters issued after joining. The central rule says no one should be employed until the letter has been issued. Build it into your pre-joining checklist.
• Using a pre-2025 template. Old templates lack the type of employment, skill category, social security applicability and Labour Identification Number.
• Vague employment type. “Contract” versus “fixed-term” matters for benefits and gratuity. Use the exact category.
• Pay figures that do not match payroll. A letter that says one thing and a payslip that says another is a dispute waiting to happen.
• Informal promises. Commitments that were never approved, such as a guaranteed raise, become contractual once written down.
• Policy text pasted into the letter. Refer to policies instead, so you can update them without reissuing every letter.
• No signed copy on file. Keep the acknowledged copy in the employee record.

Keeping letters consistent as you hire

Inconsistency creeps in when each manager edits an old letter. A few habits prevent it:

• Keep one master template per employment type, with locked statutory fields and editable role fields. Our guide to appointment letters for different employment types shows how they differ.
• Review templates whenever a rule, pay structure or policy changes, and at least once a year.
• Make the letter a step in your onboarding checklist, before system access or first-day logistics.
• Record changes formally. If designation, pay or location changes after joining, issue a written change letter and keep the acknowledgement.

Outside India

Many countries require written terms early. In the UK, for example, employers must give employees and workers a written statement of the main terms on or before their first day, with some further details within two months. If you hire across borders, check each country’s rule rather than reusing the Indian format.
