4 types of people in an office

There are commonly these 4 types of people in an office:

1) Capable and willing to do the work. They end up being dumped with most of the hard work but not necessarily have proportionate realistic recognition and be rewarded.

2) The lucky one. They are not necessarily the smartest but somehow they win the heart of the boss and go all the way up.

3) Capable but unwilling to do the work. They couldn't care less and no one can dispose of them.

4) Uncapable. Oh...well....

Do you have all of them in your office? Remember that most of the time you do not have a choice as to what type of people you want to be. You can just take it and live with it.
