probationary period
A probationary period is a specific timeframe, often lasting from a few weeks to several months, during which a new employee's performance and fit within a company are evaluated. This period allows both the employer and the employee to assess whether the job is a good match.
During the probationary period, employees may receive training and feedback to help them improve their skills. At the end of this time, the employer decides whether to confirm the employee's position, extend the probation, or terminate employment based on performance and compatibility with the company culture.
