I have been working at a company for 8 months now. My hours have always been M-F 7:00am-3:30pm. Because I am a single parent these are very convenient hours for me [one of the reasons i took the job]. Now all of the sudden without notice on friday with paychecks was a memo saying that as of the following monday the hours were changing to M-F 6:30am-5:00pm.It also stated that these new hours were mandatory for everyone. As you can imagine not only is this 50 hours a week but this creates a huge problem for me. I can not work these hours at all, and i fear come monday I will be out of a job. Can they legally do this? What are my options if any?

Unless you have a bona fide, legally enforceable contract or CBA that specifically states that your hours are x and cannot be changed, your employer can schedule you for any shifts they want, or change your hours to anything that is convenient for them. Your options are to work the hours your employer wants you to work, or find employment with hours that are convenient to you.

If you are non-exempt you will, of course, have to be paid overtime for the hours over 40 in a work week.

that sucks! Ok thanx for your help.

Your right about that lrsinma. You do have rights to organize with your fellow co-workers though, that is in the law.
