Being told by my boss to work different days. Can this company do this to me, legally?

Q) I recently was off work because I blew my knee out. I’am being told by my boss that when I come back that I have to work the same hours but, on different days than I was working. I was also told that if I didn’t work those days that I would not have a job. Can this company do this to me, legally? If, I do not accept the new schedule and the company let’s me go, can I draw unemployment “

A) Generally, unless an employment contract or a collective bargaining agreement states otherwise, an employer may change an employee’s job duties, schedule or work location without the employee’s consent. In terms of notifications, some state and local predictive scheduling laws require businesses to provide workers with advance notice of their schedules or face penalties. If you are unable to work because of injury you may consider filing a claim for short-term disability. If you are injured off the job and are temporarily unable to work, you should file a claim for short-term disability benefits. For example, if you are in a car accident and break your leg, you will likely be unable to work for a while. As long as your injury causes you to miss work for more than a week and isn’t job-related, you will probably be eligible for benefits. If you have lost your job you may qualify for unemployment benefits.
