A confirmation letter is the formal document an employer issues at the end of a successful probation period, converting an employee’s status from probationary to permanent.
Confirmation typically triggers full benefits eligibility, health insurance cover and leave entitlements that were reduced or unavailable during probation usually become fully applicable. Notice period terms usually change too: many contracts specify a shorter notice, sometimes around 15 to 30 days, during probation, stepping up to 30 to 90 days after confirmation, though exact figures are company-contract-specific rather than fixed by law. The confirmation letter also serves as documentary proof of continuous service, relevant later for things like gratuity eligibility, which generally tracks from the original date of joining rather than the confirmation date itself.
No. The appointment letter is issued at joining and sets the initial, often probationary, terms. The confirmation letter comes later and updates those terms once probation is cleared.
Practice varies by company, some formally extend probation with a stated reason, others treat a lapsed probation period as automatic confirmation depending on the contract’s wording.
No, EPF, ESI and gratuity accrual apply from date of joining regardless of confirmation status. What changes is mainly company-discretionary benefits and notice terms.
