I think that sort of relationship should really only existing for a few types of government jobs to block regulatory capture [if you have a job for life with good pay and retirement...the only way to lose it is to be caught being bribed] and teaching [which politics might meddle with].

Please don't take my comment personally. I watched people who were loyal for 10+ years get laid off recently and it kind of has made me angry about the idea of that kind of loyalty to a legal fiction.
