Suspended from Walmart for taking a lunch.

I agree with Mtn Rescue. It sounds like your boss was being unreasonable as people can be, but if he did not let you know you needed to have a working lunch, then I would contact HR to let them know this is an unjustified suspension and let them know if they continue with the suspension that you will file a complaint with the state labor board or the EEOC.

I will concur as well with previous 2 posts.

By law you are intitled to take your luch and if you choose to dose while on your lunch hour that is your choice my husband takes what he calls a catnap for ten minutes before returning to work from his luch hour. In some states if you are the only one working they can under Emg reasons ask you to only take a break but that is rare and if your working at walmart I do not see where that would apply. It sounds like to me your boss is just using that for an excuse. Have you been having any issues with your boss? I would call the labor board and get an attorney It sounds like you could have a good case.

This is a quote from FLSA web site.

When must breaks and meal periods be given?

The FLSA does not require breaks or meal periods be given to workers. Some states may have requirements for breaks or meal periods. If you work in a state which does not require breaks or meal periods, these benefits are a matter of agreement between the employer and the employee (or the employee's representative).

You need to research the laws that apply in your particular state.
