I believe my job also contributed to my ptsd, the first panic attack I ever had was at work, things have not been the same for me since. I worked in hotel maintenance which I think is a stressful job, but some of it was me. I was never willing to take a sick day, at the most I would do for myself, I would try to work as long as I could while ill, only going home after all the hardest most important tasks were finished. I also had too much on my plate, rather I would always try to do more now so that I could do less later...however maintenance doesn't really work that way, there is always more and more to do. I managed to continue my job for 6 more months after the ptsd had shown its ugly colors to me. I could have continued my job, but it wasn't my choice as I was laid off after new management came into the hotel. A huge weight was lifted after losing my job, though the advantages to having a job are obvious and I miss that.
Constant unrealistic deadlines, inspections, reports and paperwork, endless routine but with constant learning, an unsatisfiable boss and co-workers. My job also demanded that I set a complex priority sort of flow chart of tasks if you will.
If only they had assigned me partner or a worker under me, things might be different today.. But only might, because I have already had much trauma in my life. Abuse and neglect as a toddler and child, the loss of my dear father and many years of drug use and all the lovely things that go along with that all contributed to where I am today.
