I used to work for a Dept. of Employment, but that was so long ago that cavemen were required to provide their own clubs for hunting. But the primary standard for collecting benefits, then, was that were you unemployed through no fault of your own, and able and available to work (with a few ifs and ands thrown in). So if you were still employed at the time of injury, and you are now recovered, and willing and available for work (and are still unemployed), you almost certainly would have been eligible for benefits, notwithstanding that you had given notice.

I remember finding for claimants who had given, say, two weeks notice, but were terminated earlier by the employer. Why? Because the employee was willing and available to work at the time of termination.

I hope those standards still apply, and you win your appeal.
