I am a hygienist in MA, and due to the economy some of my patients have either not showed up or cancels. My boss tells me that even though I am scheduled a full day but my patients cancels I have to clock out and either leave for the day or stick around to see if any patients get filled in. I seem to think that if I am scheduled the full day and patients cancels I still should be able to get paid something whether I stay and file or not. What is the legal resolution?
