This bill aims to allow certain federal employees who are involuntarily separated from government service during their probationary or trial period to resume that period upon reinstatement. It applies to individuals separated between January 20, 2025, and January 20, 2029, who were serving an initial probationary period in an Executive agency immediately before their separation. Upon a "covered appointment" to a position similar to their previous one, the employee's remaining probationary period will be calculated by subtracting the time already served from the total required probationary duration. This ensures that employees do not have to restart their entire probationary period if they are rehired after an involuntary separation. The Act is designed to provide a specific window of protection, terminating on January 20, 2029.
