I was a happy and loyal employee for many years. Everything changed when I was transferred to a new manager and placed into a role that did not suit my skillset right before a personal life event. This manager drastically increased my workload over the next few months with no regard to my personal situation and eventually I was working 60+ hours a week while receiving no yearly increase in salary. Meanwhile I was being scolded for not being "dedicated" enough and labeled as "underperforming" because I was unable to manage an unreasonable workload. All of this led to unfairly being placed on warning and having my yearly bonus taken away because I couldn't meet my boss' unrealistic demands. After a few more months I couldn't handle being mismanaged so badly that I happily left for another company.
