Working environment is getting worse

It is 8PM and I am still at my office, well .. working + chatting + checking emails...

Employee turnover rate is so high in here that I heard that there are another 5persons who same position with me already tendered resignation letters. 1 of my production folks is leaving too.

People comes and leave, but I am still here. The day I tender my resignation letter will be the most happiest moment in my life in this company I guess.

There is another thing that makes me feel that this company is not suitable for me.

Last week, about 5pm, my manager asking a boy to take a pen and paper and jot down the names of peoples who went back already... When I was told about this, the first thing that came into my mind is .. luckily I went back after 6 that day, and 2nd thing is ... why I have this kind of thinking? I am still being borne ok? So even if she doesn't like me going back earlier, she still can do nothing to me. No harm .. and I don't care anymore about going back early and being caught by her ... lolz

If you give me lots of jobs, I can cope with it, but if I finish my job, why can't I go back on time?
