Relieved because simply he didn´t get along with the local "dance" of shifting responsibility and packaging and polishing manure so it looks high quality. Believe it or not, the process of manure processing can be very stressful. I experienced it myself as when the organization gives you 3 years to prepare for an audit but only 6 months before said audit is when management assigns people out of the blue so they can get their "certifications" and awards as best in class. And the paper chase that ensues can be very stressful. Also when some incompetent buffoon gets promoted and starts asking to do things about of which he has no idea for the sake of "innovation" just to show something to his higher ups and doesn´t take ownership for the failure because of his wasta he can generate a lot of stress.
This is besides the point of what technical/leadership skills you bring to the table. It´s just about trying to make everything and the boss look good and keep your mouth shut if it doesn´t.
Unfortunately I did not play along and when they were starting to really care about inefficiencies because of very low oil prices it was way too late.
So I can relate with the author of the original post. Some people get placed in departments where they are lucky enough to get some job satisfaction or at least have the skills to relate, make the bosses happy and just play along in the charade in their department. Purely technical people generally will find the only rewarding experience will be the monthly apology check.
So I find the sarcasm on the previous post uncalled for.
