Even staff positions, management and support positions may disappear without much notice. Please don't think you're immune from this because you've worked there x years or they're nice people. As we've seen many companies have closed or had to lay off hundreds of people due to a number of reasons.
A well planned layoff is not possible. I have watched big companies tell good artists only hours before end of day that this will be there last day. I have been laid off over the phone. I have watched artists walk out and quit just because.I have been fired for wanting to get paid overtime.
The long and the short of it. Always be prepared to move around. The bigger the company the more prepared you should be.
You should always have leads on work. Network and know where and when the work is. Stay connected with old co-workers.
You should also be saving good parts of your checks you get to help you thru the times where maybe there isn't any work no matter how good you are.
