Thanks masaegu san. I have a few more questions.

First of all, I would like to know if both 会社に勤める and 会社で働く are referring to "work at a company" instead of "work for a company"?

And also, can I say "高島屋に勤める"?

Secondly, I am curious to know if I am right to say that the difference between 椅子に掛ける and　椅子に座る is that the former refers to sitting on something (floor is excluded), whereas the latter is refers to sitting on something and also on the floor?
