You just described ageism. They replace you with that new person who can go till they also burnout. I was in one job where the average stay was a little over 2 years. It was working in Student Life at college and you were expected to work the 8 AM - 4 PM M-F and have three nightly meetings and be on call 7 days a week 24 hours a day one week a month. If there were emergencies I would be working till 2 AM and I &quot;COULD&quot; call in late aka come in at 10 AM or else be viewed a slacker. After 3 years I couldn&#x27;t hack it and they had dozens of applications to replace my position. Then they fired the whole team and just rehired. It is still that way 10 years later.
