I work in a school kitchen. One of my work colleagues keeps giving me intimidating looks and another one keeps telling me off in a really firm way. I try to stick up for myself but then I keep quiet because I am sort of scared of them. I'm on a extended probationary period until the end of the month so I don't want to go to my Supervisor because then it would be their word against mine and I don't want to be seen as the trouble-maker. Like today I was washing-up the plates and one kept giving me intimidating looks constantly and pushing past me to put the plates/cutlery in the tray racks. I kept quiet but then when I put some onto the tray racks the other one told me off in a really firm way pointing her finger at me because apparantly I was putting them in the wrong way. I said to her in what way are they going in the wrong way and she told me not to talk to her like that. The Supervisor then came and told me I could leave as I had to get the kids from school so after about 10 minutes I left at 3pm. I said bye to one of the girls who was helping me to wash-up but I didn't say bye to the other two. I said bye to my Supervisor and she said bye to me. Now I'm dreading going to work tomorrow because I'm worried incase they said anything to my Supervisor and I'm also worried to go in because I'm scared of them as well. I can't go higher up than my Supervisor as in our training handbooks it says to go to the Supervisor first. But as I said I am still on a extended probationary period and don't want to be seen as the trouble-maker. The only person I have told at work is the girl who has started at the same time as me but she tells me to ignore them and they do the same to her as well but they do it to me worse.
