For every new hire, the first official interaction with HR is more than just a handshake or a welcome email — it’s the joining letter. This document formalizes the employee’s appointment and sets the stage for their journey with the company.
If you’re a new HR professional, mastering the joining letter format is crucial. It’s one of the simplest yet most important documents in onboarding, acting as the bridge between offer acceptance and day-one employment.
What is a Joining Letter?
A joining letter (also called an appointment confirmation letter) is the written document given to a candidate when they accept a job offer and officially join the company.
It confirms:
- The employee’s acceptance of the offer
- The role, designation, and joining date
- Basic employment terms and reporting structure
- Employer’s acknowledgment of the new hire
Why is a Joining Letter Important?
For employees
- Confirms employment with the new company
- Provides proof of joining date for records and background checks
- Sets clear expectations on role and responsibilities
For employers
- Legally documents the appointment
- Avoids disputes about terms of joining
- Marks the formal start of the employer-employee relationship
Key Components of a Joining Letter Format
A professional joining letter should include:
- Employer details – Company letterhead, address, date, reference number
- Employee details – Full name, designation, employee ID (if pre-assigned)
- Joining confirmation – Acknowledgment of offer acceptance
- Role details – Designation, department, reporting manager
- Joining date – The exact date the employee starts work
- Terms of employment – Basic probation clause, salary (optional if already covered in appointment letter), and work hours
- Welcome note – A positive line to set the tone
- Authorized signatory – HR or employer signature
