Understanding creditors

Found out there is a significant delay in getting my severance AND my unemployment so I'm going to have to tell some people I can't pay them in april possibly. Paychecks end on 31 Mar and severance may not arrive for 30-45 days! I can't believe it takes a company as big as Shell 45 days to pay severance. It's not like they don't know who they're letting go and what it's going to cost! Texas Workforce Commission, I can understand. They don't know and have to process stuff to make sure I'm eligible... and they're the government! You expect them to move slowly. Major budgeting in my future!
