Sunday Roast: Am I the AH for this?

Especially when the other person has also been diagnosed as having a disability.

I know someone at work who I have been told has these tics, which can get 'very aggressive'.  Whether or not they can 'help it', I don't know.  

This person (I won't name names) is male, is slightly taller than me and fairly 'muscular'.  Until recently, he was quite OK.

But just over a year ago, the work arrangements had been changed, where some people were 'trained' on these changes and other people weren't.  I was one of the people who wasn't.  But the 'training' really only consisted of an hour's worth of pre-shift overtime.

I was never asked if I wanted to do that - and - it would have been nice to have been asked!!!

Some people were saying that I was being 'unfairly treated'.  But I let it go because I didn't care too much about it and (secondly) I didn't want to be stressed before going on leave.

But when I returned from leave, the issue started to escalate.  I had been trying to learn the 'new system' by myself and had no extras like overtime.  I had no issue still.  The people who believed I was 'treated unfairly' still reaped the benefits like overtime etc.  

However, while I was in the dark about how to do the job, someone else was assigned to help me.  And I actually wasn't getting much help from them at all.

But that wasn't a problem in itself: it was supposedly that guy with the 'aggressive tics' and I had to *show him* how to do the job.  He kept asking questions and stuff, like it was my job to teach him.

One morning after a gruelling night of doing different jobs, including breaking up heavy bags, he had the gall to say, 'I don't want to do your sorting for you!'

So my retort was, 'Well, if you're going to be like that, then please go somewhere else!'

Then I got scolded for telling him off and 'jumping down his throat' by a female supervisor who obviously has a 'soft spot' for him.  

After finishing my shift, I knocked off and went into the locker room.  And what was worse was that she came in and lectured me about how 'wrong' it was of me to walk off the job.  Really?

Then the day after, 'Tic Boy' came back under the guise of 'helping'.  According to him, it was my fault because I was 'just fiddling' and 'doing nothing'.  Also, he had told me he was going to tell that supervisor he didn't want to work with me. I already told him he was free to go elsewhere if he wasn't happy.  I told him I would rather work on my own than to be a 'punching bag'.

Fast forward a few months ago, he had gotten into the habit of making repeated noises that sound like he's spitting.  I told him off about it and he told me I was 'annoying'.

I got told off again for 'not accepting him and his tics' and told to 'work with him'.

Last two weeks, all was relatively calm between me and him.  I thought, maybe he is getting better.  But come Friday morning, he started making that dreadful spitting (or hissing) noise and I made the mistake of looking in his direction.  That's when he gave me the stink eye.

I've decided that I want to work as far away from him as possible, even if it means going to another shift.  While it might be true he has a medical condition that could be contributing to his behaviour, it didn't entitle him to act in such a way to behave so horribly.

AITA for not wanting to be intimidated by someone with that affliction?  Surely not!!!
