so sorry for the stress. I have been there done that. Also in Operations. I worked for a company 18 years. Was a supervisor. Then my boss started doing the same things. I was documenting the things my boss was saying/doing to me vs. what he was reporting. Had witnesses(my crew). Didn't matter. When I met with my bosses boss, I was told they don't want to see anymore documentation and I better not do that anymore. I was placed on probation. Each time my probation meeting was due, I would be prepared and 5 minutes prior to the meeting my boss would cancel. This went on from April - November when they terminated me. They terminated me for something I didn't do. They said they found a document printed on an office printer with my name on it. I asked them to check their server's and see who printed it because I did not. They terminated me saying I did do that.
It was a long year that year. Everything I did, as you mentioned was documented, however they seemed to have left out the part on what THEY did. HR encouraged me to fight, and go on, but when it came down to the meetings, HR would stab me in the back. "open door policY" is not what it means. Never trust HR. There was one issue I was written up on regarding FMLA. A member of my crew was asking me questions regarding FMLA, since she had a sick child. I suggested to her that she speak to HR because I am not that familiar with it. She went to HR, and was upset (sick child in hospital), and I was suspended. Because>> She went to HR crying and said I told her to go there. I DID. Yet I was suspended because she was crying.
The weekend following my termination my crew told me they had security guards there in the lunch room. One of them asked why they were there. The guard replied, "some crazy broad is going to come in here and blow the place up. She may come with her 8 year old son", and gave my description and that of my son and car. so, all the people I have worked with (and transfered from one city to the next) thought I was going to blow the place up.
I hope you have better luck than I did. I have learned to just keep my mouth shut and do my job, ignore everything else. I get things in writing as far as leave, vacation and sick time. (emails). If it wasn't for the document that I didn't print, they would of found another reason. I just hope what comes around goes around for all those who did this to me. It is very hard to move past a job I loved, people I loved working with, and the experience I had. Starting over is very hard.
Good luck.
