I like this sort of mentality in companies that think they are some sort of hot start ups that can fire anyone they feel like. I dunno how it is with management types, but this sort of approach is extremely amusing to me in niche skill areas.

For example, this happened to me a few times, but as I am 1 in 25 people in the country that can do what I do, it takes that company 12-18 month to find a replacement, if at all.
