He is ___. He will ___ to the boss if he has to, to get the position.
Basically I need to know two words here, first to define what kind of person that is using a noun or an adjective and secondly what will he tend to do.
I couldn't think of any words in English, but if it helps, I'm familiar with the phrase "ser una pelota" in Spanish. I just couldn't remember the English equivalent word of that phrase.
