Thanks everyone for your thoughts.
It wasn't unexpected....two divisions are merging and eight people including the division president were cut from mine, and even more from the other division.
My supervisor started behaving differently towards me a couple of weeks ago, and work started being diverted around me last week. By last Friday the final red flag was her asking me about six times if I have any appointments Tuesday. Monday morning I called a co-worker friend to say that I probably wouldn't be with the company after Tuesday, and he said 'gee, that's funny, I have to come to the office for a meeting too'. Needless to say, he got bounced as well.
I cleaned out my company van that morning before leaving home, and had a list of items to discuss with HR in my pocket. The HR people were shocked when I pulled it out and started asking my questions (the company is fond of the 'sneak attack' approach to layoffs).
Reg asked if I'm going to be making lemonade, and the answer is 'you bet I am'! I truly believe that better things are down the road.
