In Pennsylvania, your employer is typically not required to pay you for time spent on-call unless you have to spend your on-call time in a specific place. If you are on call but are allowed to do whatever you want until you are called in, you are not required to be paid for this time. In these circumstances, the time you spend on call does not count as hours worked when determining whether you’re entitled to overtime pay. Being on-call means a worker is expected to be available at any time during their shift, even on short notice, to perform their expected job functions.
