A lot of places expect this, and my observation is that it fuels even more twisted behavior by the companies. For example, in Academia, it's not uncommon to sue over a failed tenure case. I know of a colleague who was terminated the year before tenure review, because (from what I gather from scattered conversations) his case was expected to be controversial, and it was much easier to fire him now, where the process is not well-defined and not transparent, instead of going through the whole process and having everything scrutinized in courts.
