I left a company a while ago because it was seriously lacking in proper management and a reasonable workload for its staff.
Multiple colleagues were off with stress caused by the job and some were on anti depressants to combat it.
It's not the first company I've worked for where it was common for people to be on sick leave with stress.
AIBU to think more needs to be done to force employers to take their staffs mental health seriously. It is not okay to push employees to depression with huge workloads and poor management.
I often found the unpleasant changes for staff coincided with thicker lining of management's pockets.
