Actually, it works quite different. Because laid off and expecting recall isn't the same as fired for cause. It is what we call a "clean separation" issue, where the employer did not dispute the claimant receiving benefits in the first place, with the assumption that if he has work in the future, the employee will agree to return to work for him.
But if the employer is crafty in this particular case, he's got the guy back to work for him. No unemployment claim approved. He'll work this young man all right, once he gets him back in. In other words, he'll ride this person, demean his performances, give no warm fuzzies. He'll insist that the young man do the dirtiest and least desirable jobs. He'll give him poor performance ratings. He'll grade him harshly, speak to him negatively.
And heaven help the young man if he's tardy or absent without a call in. Within a short time, the young man will be so frustrated he'll either walk off the job due to "harrassment" (which will be tough to prove consitutes a "good job related reason to quit" and receive unemployment in these circumstances) or be fired for tardiness or insubordination or absenteeism. These are much more justified reasons for firing in unemployment law.
If you are laid off and the employer recalls you, you have to go or be stopped from receiving unemployment. But if you have been terminated/fired for cause/canned/ whatever the term, the hiring agreement has been severed. Calling the employee back to work in these cases isn't quite legit, and more than likely will not result in stopping benefits if he refuses to go.
Of course, it is possible that the two parties have had a "heart to heart" outside the venue of the unemployment office and the worker has agreed to come back to work. It's probably not a wise move on his part, but it could happen. Nothing says he can't agree to go back and stop the unemployment appeals process at that time.
