I work in a factory and I really enjoy it. I got hired through an agency who are my boss aswell as my supervisor who is my boss aswell. But I work on a line where there's a line lead, I rarely work under her unless I have no work but she gets on very well with the supervisor, she gets her way, so before I started I had 3 holidays booked one for each month bar one month, 3 days most on Saturdays out Thursday and Friday. I'm there 4 months, but the line leader has said to me how did you get the holidays repeatedly about 6 times she couldn't understand how I got them, I explained I had them booked months ago, I heard she's supposed to be finished at half 1 but stys till 4 and complais about how she can't get holidays. Then one of the girls said that she's bitchy about me saying she's off on holidays the whole time and she just in the door and she wants to get moved to evenings and she gets it. Then I get an email to say I could be facing disciplinary warning depending on the outcome of a meeting on Monday. Should I leave or wait till the meeting, why she's jealous of me I don't know, like she's owed holidays so take them
