In Pennsylvania, only employers of seasonal farmworkers are required to provide breaks. These employers must give employees a 30-minute break after five hours of work, during which employees must be relieved of all duties. This time may be unpaid. All other Pennsylvania employers have no obligation to provide either meal or rest breaks.
