I am a registered nurse who works for a large hospital in Pittsburgh. We are required by our employer to change our clothes into hospital scrubs before and after our shift. They do provide us with scrubs. Some of us take our scrubs home to wash them as we are allergic to what the hospital washes them in. Our employer, however, does not allow us to change on the clock. We have to change before we clock in for our shift and clock out before we change to go home. This requires arriving early to leave time to change. They are now threatening us with disipliary action for wearing our scrubs to work and home because we are not allowed to change on the clock. Is this legal? Shouldn't we be allowed to be on the clock while changing since it is required for the job?
