Xiamen:
very easily, just have a little more sick days then they allow you, get a warning for that, have a repeat some where during training and voila another warning on top.
So by incident be late for your pick up once or twice and guess yes another warning in your file.
As you are now cornered, you do your best but unfortunately you forgot your hat in the company car and so you have it ....you can now be fired
please note those are only examples of what happened to guys here.
Creativity of the company is huge so any other incident e.g drinking espresso out of a china cup on board can start the same chain of warnings, bullying.
I suggest you come here and find out by yourself.
