I have a question about nursing and labor relations and legal issues?

My boss is leaving threatening messages on my phone machine, and writing notes that It is unacceptable to stay after your shift to get your work done. She states that even 15 minutes is too much. I work on a very busy Surgical floor, and it is not possible to get the work done in time. If you leave without doing something like charting, your license could be on the line. My fellow workers are punching out, and then going back on the floor to finish their work. They are doing this in fear of their job. I am refusing to do this because I refuse to work for free. I do not try to stay after, I would rather go home, but most of the time it is just not possible. Any suggestions?

Keep the threatening messages and give copies to your human resources department asking them to help. If they do not help, you may need to hire a lawyer or get a government labor agency involved. Unfortunately, unless you are under contract they are pretty much free to fire you if they want. It would be your burden to prove they are firing you because you are standing up for your legal rights.
