Abuse of Power

Need help... hoping someone will have advice. This is an emotionally charged situation, so objectivity is the key for me. There are other workers in this particular organization who are feeling "unheard" and vulnerable. Because I had previously been a manager in this organization, I am very familiar with the hierarchy, and have suggested in every instance that the employees approach the general manager to voice concerns and work to resolve the stressful situations they find themselves in. (with HR dept. being the last resort to contact, as any good manager will want a chance to resolve the complaint first) When I approached the general manager with concerns, I was told that "this is not a good day to discuss these issues". There was no follow up to my request to discuss my concerns.

My situation is critical, as I am off on sick leave and being treated by my family doctor for clinical depression, brought on as a direct result of work place stress. I have worked for the company for 8 yrs, and have always rec'd good annual reviews, and would have been considered a very productive and valuable contributing member of the team. When the management team underwent changes, and new members replaced existing managers, there seemed to be a concerted effort to "replace" those of us who were part of the "past" team. When I
received my performance review, it was extremely poor, with a "needs improvement" rating.

I was shocked by this and in fact felt as if I was being penalized unfairly because I had voiced concerns a few months earlier to our HR dept. The supervisor actually sited this as part of the problem... my being resistant to following the "chain of command." I refused to sign the document without reading it for myself first, and asked for a copy to review. I was not given the chance to read it nor was I given a copy of the review.

I am trapped in this situation, due to the poor performance evaluation I cannot be transferred and I can barely meet the criteria of my job now, as this supervisor delegates unrealistic task completion times, or includes job duties that I am not normally requested to do. Again I am feeling as if they are deliberately trying to force me out. Due to restructuring at our corporate level, the people whom I would normally liaise with are no longer in that position. (or they were not available at that time)

I desperately need advice, as I need to return to work, but am extremely anxious that my situation will be made worse, especially in view of my sick leave, and the fact that nothing has been resolved on my behalf.

What are my rights? How can I protect myself from bullying or abuse of power by this group of management? I have always been a hard working productive team member... until these past few months where I am categorized as NOT meeting my job requirements, by these new members (with whom I directly report to) This has seriously affected my health, and I am very worried about my future.

Any help is greatly appreciated, and I thank you for taking the time to respond.
