I had a boss that drove me right to the brink - Seriously, and the other supervisors were either worse than her, afraid of her or indifferent to her actions. There was a high turn-over rate in the organization and this woman was the reason for many of the resignations.
She was/is an insecure, emotionally unstable micro-manager prone to shouting out orders, snapping at anyone she did not find useful [those under her]. There was nothing that could mitigate her rages, anticipation of her needs lead to her suspicion that you were "trying to show her up" or "angling for her job". If you asked questions, you were described as being incompetent, [saw it happen and it happened to me], and if we worked in a group solve an issue, we were "know it alls".
Crying before leaving for work, crying in the car outside work, and crying in bathroom stalls at work that became my reality, others drank, still others just zoned out and became the worse representation of what she said she had to work with as staff.
She locked me in the office archives [that has no cell-phone reception] and let me know that I would only be released when I found what she wanted, I reported this - nothing but abuse from her was the result. She tried following me home on several occasions and asked me why I never went straight home after work. Anytime I put in for a training opportunity, she indicated to management that she couldn't spare me, or sign-off on my training.
I swear the stress gave me my fibroids, that developed over the time I worked there. There is no family history of fibroids among the 23 women in my direct and extended family or in the women on my Dad's side of the family. I was worn out and sickly all the time I worked for that creature.
It stopped when I just could not absorb anymore abuse, I stopped her one day during her regular tirade of disrespect. She had me spearheading a project with a time-dependent deliverable and covering her duties while she was out on an emergency. She gave 5 different deadlines to the Head of Department and other Supervisors respectively. They each told me a different deadline, and when she contacted me I brought this up and asked to be e-mailed the specific deadline and specifications than getting the info via word-of-mouth. I was blasted, and told that I should know my place and be "happy" that I was being included and given this opportunity. I just said that I couldn't work with such inconsistent information and directives it was easier than I ever imagined, with the expected outcome of her poisonous abuse, and her trying to destroy my reputation with any and all people that would listen.
I am no longer working there.
I am healthier, financially stressed, but happier and more productive than I have been in years.
