It does not need to be that complicated :) When a company I worked for was bought the new companies tried to lay of some (most) of the employees. At this time our team was working on a product that was to a large degree implemented in Scheme (because management didn't really care about the programming language). I quit at the company (for unrelated reasons) soon thereafter, but it seems that my colleague (with whom I've implemented the system) had quite a good job security at this time.
