Nervous at work

I work for a city government and have for 15 years. Last Friday they laid 70 people off and said it is just the first round. I think I am safe right now, but it sure is uneasy times when friends of yours in the organization are loosing their jobs. City Managment is going before City Council next week to outline where the next round is going to go. 2500 of the 4000 employees are police and fire so I know they are going to take a big hit in the presentation. I work for Utilities so feel somewhat protected because we are a big source of revenue for the city. The department manager made some organizational changes last January that really sent me into a deep downward spiral that I am just crawling out of. I don't want to go through that again. My relationship with my wife is still suffering from that episode.
