I am so glad I'm in a unionized work environment. I started entry level in the fileroom with tremendous anxiety and yes fear or management. Prior to that job I suffered with terrible nerves on the job even though I was intelligent and capable. Starting entry level and having time to get used to the job, familiarize myself with the next step up helped me to cope with moving up. It kept the excessive anxiety just bearable. One temp promotion I had severe anxiety but coped by listening to meditation on the way to work, at work and going home. I did CBT exercises to deal with my fears and faced and accepted that I might fail. But in the end I did okay. Meds have helped me cope by reducing my anxiety and improving my confidence. Experience has helped a lot too. You're not alone in this struggle.
