My job used to be fun and I loved it, until incompetent management took over and wrecked it for everybody.
I put up a sign in the office:
It is impossible to be competent in a dysfunctional enivronment.
The stress went out of sight. My psychiatrist gave me 7 weeks off (with paid leave). My doctor has been afraid I have PTSD. I wasn't the only one. Sick leave for others increased. One guy they hired came, worked 6 days and then quit saying, "You guys are crazy". There have been lawsuits....
That all changed when they RIFfed me. Best thing really: Healthier and happier, retired, lost weight, better living conditions. I still get up early, but not to solve problems caused by carelessness -- My cat wants to be fed. We commune for awhile. It's all good.
Bad management.
Dysfunctional workplaces.
Cause and effect.
