What to say to your boss to keep your job?

The following are all in my opinion:

1) disobedience

2) willingness to work

3) quality production (e.g. if you work as a chef you produce good food, so basically doing a job well)

4) manners

5) intelligence and understanding in your field (e.g. if you work as a mechanic, you are required to have an understanding of mechanism )

6) fair communication skills (no matter what you're job, you're expected to communicate with society; even if you're self employed, you're not going to make good business if you keep to yourself!)

Those are the guidelines of any job, higher jobs will obviously require more; such as, if you work in an office you are expected good ICT and organisation skills. Think about your job and add to that yourself what you think you need.
