I am unsure if some actions/restrictions that my boss has taken against me may be a violation of the ada psychiatric rules. I have major depression, for which I have been diagnosed and am under treatment for (medications). Because of this sickness, I have difficulties interacting with co-workers. Most of my co-workers are unaware of my illness and simply consider me 'a jerk'. I also believe that my manager feels the same way. On my performance reviews I get high marks for my ability to do my job and low marks for my relationship with co-workers. He has told me that there have been a large number (compared to other employees) of complaints about my behavior, however, he has never made these compants know to me until my review interview and has given me no opprtunity to dispute or explain them.
I work in a manufacturing enviroment which is based around a large number of machines. He has set up the personel work schedules and rules conserning overtime so only I and one other employee, of which my manager has made public his dislike of, have zero opportunity to get overtime. The machines I work on have basicly 24/7 coverage, but there are other machines in the building that are not covered 24/7 and have plenty of work availible( I would need traning to run these other machines). He has said that if I get extra training and get the promotion it would lead to, overtime may be availible. But because he will not allow anyone to get overtime for training I would have to do this training during my regular shift. This would be very difficult as the machines I work on require a lot of monitoring. Both of these rules (no overtime for training and a requirment of the title from the promotion to get overtime) are not in the employee handbook and have only been used sence this new manager started. The promotion requirment was added after the second time in a few weeks that I asked for overtime The past manager encouraged employees to train all the wanted and would allow overtime, to an extent, to get this training.
My HR manager is currently unaware of my sickness and I am not looking to sue my company or looking for them to change past performance reviews, I just would like to know that if I go to my HR manager with this situation, can I make a case for discrimination under the ada and and get the HR manager to make my manager make overtime availible to me.
Thanks to any who can help me with this.
