At my last job, my limits were also tested, but in a different way. I could have stuck it out there for a while. I was unhappy, but not upset. This job upset me. I was in physical discomfort and mental strain for most of the few days I was there.
It was the "method" that the boss used to train that was so stressful. It was hovering, micromanaging, correcting me as I wrote an email or a document--I have never in my life experienced such a lack of trust or confidence in anything I did so much as I experienced this past week. I know I'm knew. I don't expect to get it all right the first time. I'm happy to have somebody look over my work before it's sent out or filed away. But I'm not an idiot--I haven't gained the skills I have through luck or chance. I know that if somebody rewrites my work, it's not because it was so unsatisfactory it couldn't be used. It's because they have too much focus on how "they" would do it.
So, as evidenced by this post being a little later than usual, I've fallen behind because of the tumult this job caused me. I was too exhausted and stressed to get much done over the past few days, but I'm trying to get back on track.
Know thy limits.
