I got a new boss in 6 months ago. She is awful. Negative, patronising, egotistical, criticial, constantly complains about people behind their backs etc. Makes zero effort to be encouraging and supportive, ice queen personality. When she started I had many bad vibes and after a few weeks I wanted to leave. My post used to be very interesting but due to the negativity and criticism from this boss my mental health is suffering. I am not sleeping well and having bad dreams and have lost all enthusiasm for the role. I have a young family and feel my job is bringing me down in other areas of my life. I used to love my job but now dread it every day. I am paid well but can afford to not work for a months and use savings. At the same time, if I were to resign, I am worried about finding another job whilst being out of work. Applying for jobs is draining in itself and I am worried if I were to resign without another job lined up I might sink into some kind of depression, especially with lockdown/near to Christmas. Then again I might feel liberated by being free from this job. My boss really is a horrible person and I feel my self esteem has really suffered lately thinking about my job constantly and all the critical things my boss has said to me recently. So, aibu to resign?
