Interrupted FMLA

An employee is going out on a 3-week family and medical leave. She has asked to come in and work one day about a week after her minor surgery because she does not have backup to perform one of the job functions. If her doctor approves it, does the FMLA allow it?

With a doctor's release that it is okay for her to work the one day, I don't see a problem with it as long as it is her idea to do so. If the company is requiring her to come in, then I think you would have an issue.
