Regarding my Resignation

Hi,

I have been here for 4 months (Bahrain) now and before I came here my employer said after 3 month he will increase my salary. But now I am pretty sure he won't do that and there are many of them having the same issue. They promise me everything before I come here and now I am totally disappointed. They are dropping us to our sites on-time and picking up us after 2 or 3 hours late. They are not paying overtime, I worked even in holidays in last 2 months but still I am just like a labor to them. Now I am going to have accommodation issues.This is can't acceptable. They cut my salary without inform me in last month luckily I fought with them and got it back. I can tell you one thing my employers in Sri Lanka are like gods for me now. I am planning to go back to Sri Lanka and I am going to write my  resignation letter.

I have to give them 3 month notice according to my appointment letter. I am aware of Bahrain Law and people are saying so many different ways to do that and I am confused now. Please guide me to get this done and get back to my mother land. Do I have to got to LMR ? or I just have to post my letter by register post?  Should I take legal action? Please guide a way to get my passport back. Even my passport is with them right now.

Thanks and Regards,
Lasantha
