Trial period extension: How can I extend the trial period?

The duration of the probationary period is always the focus of labor law discussions. The starting point is often identical: the parties to the employment contract have agreed on an open-ended employment relationship that begins with a six-month probationary period. The probationary period is coming to an end without the line manager being able to get an exact picture of the professional and personal qualifications of the new employee. It is possible that the employee still needs some time to familiarize himself with the job, or he was absent due to illness during the probationary period, or the manager changed during the probationary period.
