Appointment Letters Are Now Mandatory: What to Include

In forceSection 6, OSH Code 2020

Short answer: Yes. Under the Occupational Safety, Health and Working Conditions Code, 2020, every employer must give each employee a written appointment letter on appointment, in the form and with the information the appropriate Government prescribes; existing employees without one get theirs within three months.

Appointment letter checklist: what the Code fixes versus what the rules prescribe

The Code does not print a field-by-field template. It fixes some things itself and hands the rest to rules made by the appropriate Government. This clause-by-clause checklist marks which parts of the appointment-letter duty are mandatory in the Code text, which are set by prescribed rules, and which are left to the employer, with the exact basis for each.

Element of the appointment letterWho sets itMandatory or optionalBasis in the statutory text
A written letter of appointment is issued at allThe Code itselfMandatoryEvery employer shall issue a letter of appointment (Section 6(1)(f))
It goes to every employee, not a chosen fewThe Code itselfMandatoryDuty is owed to 'every employee' on appointment
Timing: issued on appointmentThe Code itselfMandatoryIssued 'on his appointment in the establishment'
The specific information the letter must carryPrescribed rules (appropriate Government)Mandatory once prescribed; fields not listed in the Code'with such information ... as may be prescribed'
The form or template of the letterPrescribed rules (appropriate Government)Mandatory once prescribed; format not listed in the Code'in such form as may be prescribed'
Back-issue to existing staff who never got oneThe Code itselfMandatory, within three months of commencementEmployee not issued a letter on or before commencement must receive one within three months
Extra voluntary clauses beyond prescribed contentEmployer discretionOptional; the Code neither requires nor bars themNot addressed in the statutory text (inference)

Grounded in Section 6(1)(f) of the OSH Code 2020. The Code does not enumerate specific fields, so this maps the components of the duty rather than a field list. The final row is an inference from the Code's silence, not stated text. No figures in this table are illustrative.

The rule in plain words

Section 6 of the OSH Code lists the duties every employer owes, and clause (f) turns the appointment letter from good practice into a statutory obligation. Every employer must issue a letter of appointment to every employee at the time of appointment. The letter must carry the information, and follow the form, that the appropriate Government prescribes.

The duty is not limited to new joiners. Any employee who was already working and had not been given an appointment letter on or before the Code commenced must be issued one within three months of that commencement. So the obligation reaches backwards to document an existing workforce, not just forwards to new hires.

Two things the Code fixes on its own: that a letter must be issued, and to whom and when it must be issued. Two things it leaves to the rules: exactly what the letter must say, and what format it must take. That split is the whole point of the checklist above.

A worked scenario (illustrative)

The only counting the Code itself requires is the three-month catch-up window. There are no statutory amounts to compute here, so the figures below are illustrative and used only to show how the timing works.

Exceptions and fine print

The Code does not list the particulars of the letter. It says the information and the form are 'as may be prescribed by the appropriate Government.' Until, and except to the extent, those rules specify fields, the Code text itself does not tell you the exact clauses. The compliant answer is to follow the prescribed form once it is notified, rather than a self-made template.

The three-month catch-up applies only where an employee had not already been issued an appointment letter on or before commencement. An employee who already holds a valid letter is outside that catch-up sentence.

The letter's required contents can vary because the Code points to the appropriate Government rather than a single national template. The precise meaning of appropriate Government is not defined in the provided text, so which government prescribes the form for a given establishment sits outside this section.

Where the letter's contents come from

The OSH Code is a framework statute. It creates the duty to issue an appointment letter and delegates the detail to subordinate rules made by the appropriate Government. That is why a compliant appointment letter is defined by two layers: the Code, which says a letter must be issued to every employee on appointment, and the prescribed rules, which say what goes in it and how it looks.

For HR teams the practical takeaway is simple: do not expect the field list to live inside Section 6. Watch for the notification that prescribes the form and the information, because that is where the field-by-field content is fixed. Section 6 tells you the duty exists and who it protects; the prescribed form tells you how to draft the document.

How this duty fits an employer's wider Section 6 obligations

Section 6 bundles the appointment letter with other core duties. Alongside clause (f), an employer must keep the workplace free from hazards likely to cause injury or occupational disease, comply with occupational safety and health standards, provide free annual health examinations to the age groups or classes of employees prescribed by the appropriate Government, and ensure no charge is levied on any employee for safety and health measures such as medical examinations. Placing the appointment letter inside this set signals that formal documentation of the employment relationship is now treated as part of workplace safety and welfare compliance.

For factories, mines, dock work, building or other construction work and plantations, Section 6 adds heightened responsibility for the safety and health of employees, workers and others on the premises, and for safe plant, systems, handling of substances, training and safe access. Manpower and staffing firms deploying workers to such sites therefore carry duties well beyond the letter, and the appointment letter is the documentary starting point of that relationship.

Frequently asked questions

Is an appointment letter legally mandatory in India now?

Yes. Under Section 6(1)(f) of the OSH Code 2020, every employer must issue a letter of appointment to every employee on appointment. It is a statutory duty, not a courtesy, and it also reaches existing employees who never received one.

What must the appointment letter contain?

The Code does not list the contents. It requires the letter to carry the information and follow the form prescribed by the appropriate Government. The exact fields come from those prescribed rules, not from Section 6 itself, so employers should follow the notified form rather than a self-made template.

We have old employees with no appointment letter. What is the deadline?

Any employee not issued an appointment letter on or before the Code's commencement must be given one within three months of that commencement. Employees who already hold a letter are outside this catch-up requirement.

Does the duty apply to every worker or only permanent staff?

The text says the letter must go to every employee on appointment, with no carve-out stated in Section 6(1)(f). For manpower and staffing firms that deploy workers to client sites, that means each deployed employee, subject to the prescribed form and information.
