Severance and unemployment, do they overlap? after 15 years as a logistics coordinator

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. Did you file straight away?

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

Before signing, I asked a friend who is a lawyer to look at the agreement. It was a short conversation and worth it.
