<human>: Summarize the given text in a few sentences.

So I've just started my first ever job, sales assistant, and I just got my first ever paycheck. Except it was a lot less than I was expecting, £300 less, even deducting tax that's too much and indeed when I looked at my payslip the amount of hours I worked that month did not match up with the figures on my slip.

I decided to tackle this problem right away, but my manager wasn't in this morning so I spoke to the duty manager who agreed something was definitely wrong and I wasn't the only one who'd been paid less than was right. Some of my co-workers overheard this conversation and began to ask me questions about my pay, and I thinking they just wanted to help me told them everything.

So later my manager comes in and I tell him I'd like to speak to him, he says it's fine. Later he comes back and asks me to step into his office. He sits me down and tells me he's really unhappy with me because I number of my co-workers have gone to complain to him about their pay. Apparently I have a higher hourly rate than many of them even though they've worked in the store longer, are older and/ or have a higher position than me. It has something to do with the change in minimum wage, haven't totally understood that bit.

Anyway he then says he has six new sales assistants lined up for Christmas and will be letting some of the permanent staff go to replace them with Christmas temps. He then tells me some vague stuff about complaints about my communication and when I ask for examples so I can fix them he waves it away. He basically ended the conversation by saying if he doesn't think I'm amazing by this Saturday he'll replace me.

Is there any advice you can give on what I can do to try and salvage the situation?
<bot>: Boss seems to want to fire me for accidentally exposing the unbalanced pay scheme at your place of work. What do I do?
