Hi, I am so sorry, work stress is very difficult!  Here's my advice as a manager:

* Document document document. In writing if possible. Gather and organize, in order, newest on top, what incidents you have. Maybe go back a couple months or more if it's do-able. (request/what you did - including examples/response of manager/your followup/response/outcome). Spreadsheet it or table of contents it and page number it for quick reference.

* If you have a meeting or offline discussion with anyone who gives you grief, take notes every time. Date it, note who you spoke with and who was in attendance if others were there. Write up your notes afterwards into a cohesive outline. Keep your feelings out of it and document the facts. Put these too in order of most recent on top. I use OneDrive for this and it works great.

* If you've reported things to HR, document that again, in detail, with examples. Same as above.

Then you can schedule a meeting or have your documentation ready to go. You likely won't have time to do a very thorough one before the end of the week but you could have a couple solid examples of the issue.

Ask them to give you specific, really specific, examples of what is going wrong, and what exactly they want you to do. Platitudes, complaining about your "work" is not legit. They should be able to give you a list of specifics, period. If they are not speciific enough ask for more specifics or clarification. I'm betting they will not want to do this.

I hope you are looking for a new position!  I think you are but don't give up!

My dad once have me some good advice. He said that after a few years it will become clear whether or not you are the "golden boy" at your job, and if you want to advance and you aren't the gb the only way is to change jobs. If that isn't possible, what i would do is my job, no more and no less. Calmly ask for feedback and act on it as many times as it takes and keep collecting the paycheck until you retire or find a better option. 

Came back to add i just gave notice at my job. There were safety issues that were just part of the normal job that i didn't want to deal with anymore. Plus i could tell that the company valued and promoted people on qualities i don't possess and are impossible to acquire. But i get the feeling of being stuck. I wasn't looking but an opportunity finally presented itself. 

I get it.  I was a Sr. Manager at my first employer out of my BS.  It took me 6  years to garner that promotion though I had several prior.  I was matrixed to a Director who very much resembles BB.  He had a minion who was his power point Ranger.  He was the golden haired boy for the Sr. Exec who ran operations in that city.

He had a bad Napoleon complex. Little, domineering, etc...  He ended up promoting very young inexperienced people into Sr. roles as he ran off the experienced high performers.  One was a young woman who he would entertain in his hotel room on business trips. I was on several trips with them and watched her do the walk of shame out of his room in the AM as the team started to head down for breakfast.  I eventually got into a contentious position with the director I was matrixed to.  I had to get HR involved. He had already run off a solid HR generalist so HR assigned a rock star who was a lesbian thinking that he would town his crap down.  He had a habit of ridiculing people in his every AM staff mtg.  I was at work late one day and watched him go into the conference room and set the clock ahead. He left. I corrected the clock before I left that evening.

He had used that trick several times.  I filed a hostile work environment complaint with HR.  Told them to please have an HR generalist outside of the conference room every AM.  The next AM I left my office for the staff meeting. He walked out of his  office a few steps ahead of me. I walked into the room a half a second behind him. He turned to me, told me to leave  pointed at the clock and said "You are late." I replied not according to the clock on the wall, he went pale, looked at the clock which was correct.. Then I looked at mey watch, told him that I was actually 2mins early according to the atomic clock website I set my watch to every AM before his meeting.  He then started grilling everyone in the room one after the other about not doing what he had instructed all of us to do. He had demanded that his whole Sr. staff team fill out the project application for the CEOs award.  There could only be one application per project open at a time so we all had spent time the day before sitting around a screen while one person typed. After far too long I stood up, announced that I had other priorities, my peer also stood up and we left with everyone but the one logged in following us.

After he backed off on the being late bullshit he went around the room hammering each person one after the other. Standard practice for this guy.  People would carpet scope staring at the floor trying to avoid his wrath. I was sitting to his Left.  He went around the table then landed on me last started ripping me a new asshole for disobeying him. I pushed back, he started yelling about what my boss would say if he called my boss. So I said lets find out and hit redial on the speaker phone in the conference room.  I had called my boss's desk just after correcting the conference room clock the evening before.  I had spoken to my boss early that AM telling him that he would likely get a call from the asshole.  When I had filed the hostile work environment complaint with HR he and his boss and I had a meeting. They were fully in the loop and told me that they would have my back.

When I dialed the speaker phone from the CR in front of everyone the little man syndrome Director stood up smashed  his fist down on the top of the phone and lost his shit. I leaned back, opened the CR door and asked the HR rep to enter the room. She had heard it all.  She asked everyone to leave the room except for she and the director.

Not long after that I got a call from HR and corporate security. They were investigating complaints about him having inappropriate relationships with young women. He and his wife just had invitro twins. One of the young women he was banging on business trips would watch their kids occasionally.  He promoted her to a Sr role that she had zero clue how to do.

Not long after that he was transferred to lead another division.  A former boss of mine was on that team.  She called me before he was transferred to ask me about little man.   I gave her the full meal deal info.  She called me just after he showed up, called the whole team into a conference room introduced himself telling that he knew they knew who he was, he did not give a crap if they liked him or not, and if they crossed him he would destroy their careers.

I got RIFd a few months after that.  So much for my boss and his boss having my back.

My phone rang a few months after that. Little man/Napoleon complex and his minion were fired. Little man was escorted out by the Federal Marshals.  He had started a consulting firm in his wife's name, signed contracts with that firm, and then used company employees during work hours to do work for his consulting firm.

Both of them were terminated and told not to use the company as a reference or include their time with the company on their resumes. 

I did the right thing and reported the crap. It cost me the first phase of my career.  I had been with that company for 8 years.  Though I am glad that I did the right thing.

To stop playing around with you or you will sue them. Public sector doesn't like being sued.
