Every employee receives documents from a company before joining.
Two common documents are Offer Letter and Appointment Letter.

What Is an Offer Letter?

An Offer Letter is a formal document given to a candidate before joining a company.

It usually contains:

• Job position and department

• Salary offered

• Joining date

• Probation period

• Other benefits

Key points about Offer Letter:

• It is usually not signed by the employee initially

• It is a preliminary document, not a full legal contract

• Employer can withdraw or change terms in some situations

💡 Example:
If a company offers you a job via email, that email is considered an Offer Letter.
It shows that the company is willing to hire you but does not guarantee permanent employment.

What Is an Appointment Letter?

An Appointment Letter is issued after the candidate accepts the offer and joins the company.

It is a formal legal document that confirms your employment.
It usually contains:

• Job title and reporting manager

• Salary details and allowances

• Joining date and probation period

• Work location

• Terms and conditions of employment

Key points about Appointment Letter:

• Must be signed by employee and employer

• Serves as proof of employment

• Used for salary, PF, ESIC, and legal purposes

💡 Example:
After your joining, the company gives you an Appointment Letter.
It acts as evidence that you are officially part of the organization.
