A probationary period, often called an introductory period, is the first few months of employment, commonly 60 to 90 days, during which an employer closely evaluates a new hire's fit and performance. In at-will states it doesn't change legal rights, but it gives structure to early feedback and decisions.
Key takeaways
- Common lengths are 30, 60, or 90 days, sometimes up to six months.
- In at-will employment, finishing probation doesn't create job security unless policy says so.
- Under the ACA, health coverage waiting periods can't exceed 90 days.
- Montana is different: its wrongful discharge law ties protections to the end of probation.
How probationary period works
During the period, the manager sets clear goals, gives frequent feedback, and schedules check-ins, often at 30, 60, and 90 days. At the end, the manager confirms the employee is meeting expectations, extends the period if the policy allows, or ends employment.
Calling it an "introductory" period is a common choice, because "probation" can imply that employees who pass gain protection from at-will termination. Handbook language should say clearly that employment remains at-will after the period ends.
Benefits rules interact with probation. Many employers start benefits after a waiting period, but the ACA caps group health plan waiting periods at 90 days. Some employers also restrict PTO use during the first months.
Probationary period example
A new IT support specialist has a 90-day introductory period. At 30 days, his manager notes he's closing tickets well but missing documentation steps. At 60 days, documentation is fixed, but escalation decisions need work. At 90 days, both have improved, and the manager completes a short review confirming he's meeting expectations. Our probation review completion email and 30-day check-in email templates help structure these conversations.
Why probationary period matters for employers
Early months decide whether a hire works out. Feedback in the first 90 days is cheaper than a later separation, and it improves quality of hire. Workers aged 25 to 34 had median tenure of just 2.7 years in January 2024 (BLS, median employee tenure, January 2024), so getting new employees settled quickly matters for retention too.
Onboarding software can schedule check-ins and reminders automatically, so managers don't forget the 30-, 60-, and 90-day conversations.
Common probationary period mistakes to avoid
Implying permanent status after probation
State that employment remains at-will.
No feedback until day 90
Check in early and often.
Health waiting periods over 90 days
The ACA prohibits them for group health plans.
Inconsistent extensions
Apply extension rules evenly across employees.
