Severance and unemployment, do they overlap? - 13 weeks in

My employer is paying severance in instalments and I am not sure whether to file now. I would rather hear the honest version than the polite one. I have a mortgage and need to plan. Who should I ask before signing?

Keep everything in writing and save the confirmation numbers. It saved me later.

I filed on day one anyway and reported the severance honestly. The agency decided what to do about the timing.
