I am 66 years old. I have been working as a dispatcher a this company for 3 years. My shift was Monday to Friday 7:30 to 16:30 Monday to Friday. I have been advised that my new job will be 4 days on and 4 days off 5:00 am to 17:00. Can I refuse this position? What if I refuse can they fire me? Thank you

It is a significant change that you are not obligated to accept. If they fire you because you refused the changes then you should give us a call. In fact I recommend that you contact us before you decide whether to accept the new schedule so that we can explain your options and help you to make an informed decision.
