On-Call Time
If you are required to stay on the job site or very close to it and cannot use the time for your own purposes, you are more than likely “on-call.” This means that under the FLSA you should be paid for this time as hours worked.
A common example of being “on-call” is a hospital employee who is required to stay at the hospital but is allowed to eat, sleep, watch TV or engage in other personal activities. These employees must be paid for the time they are “on-call.”
