I want to ask forumers' opininon here, here's what happened to me.

I was chased out from my working place by my store manager, he's stated "to not coming back at all after I stepped out of the workplace", Is that the same as fired?

Then, I ask my HR, what to do, since I still want to work. He told me to go back working as usual even though everyone 'pulau' me there. Yes, I'm going back to work as usual and yes, everyone 'pulau' me already. My store manager of course doesn't even look at my face at all. He already issued a warning letter for small fault that i did. Actually, I found all his accusations in the letter is truly ridiculous coz he actually let other workers to do it but not me, yet issued me a warning letter. He didn't give me the letter yet, but he already handed it to HR.

Now, the HR is handling my case. I already requested to be transfered to other store, I'm not sure it's approved or not. The worst thing could happen to me is when the warning letter issued, I'll lose all the benefits included annual bonus, shrinkage bonus and incentives for a year which is a lot and costs me a very big loss.

Now, I'm stuck. If I left my job, it'll be very hard for me to get a new job since my record is now bad due to the f*ckin letter. I can't find a new job yet, and I'm sure words and rumours are spreading around about me, and I think the new place is most likely to be the same as my previous one since I was given the 'letter'.

I want to know, what should I do now? what should I do if all my bonuses taken back for a year (it's a big amount though)? How do I fight back in this matter?

Just got a job offer, and they want me to start quick, like first day January quick. Obviously can't quit abruptly from my current company. Can't tell them I got another offer, because as I've heard it'll make me look like a jerk. So what do I say to my boss/hr? Obviously I have to lie, what do I say?
