My manager is a decade younger than I am, and she was promoted over me even though I have more experience. Earlier this year, I was furloughed due to covid impact on economy/business for three months. After my furlough ended, I went back to work. I noticed that my manager hasn't returned some of my old tasks to me and kept them to herself. I thought that was a bit odd in spite I did a great job doing those tasks in the past. I wonder if my manager is trying to get me to quit my job due to lack of workload?
