Polish Labour Code (Art. 128: Working time definition)
Working time is the time when the employee remains at the disposal of the employer in a work establishment, or in any other place designated as the place of performing work. The period of employee’s remaining at the disposal of the employer starts from the moment of employee’s arrival at a specified time in a work establishment or any other place where work is to be performed and ends as the working time ends or later, if the employee has been obligated to work overtime. The time of employee’s commuting to work from his/ her place of residence and back is not to be considered as working time.
