Would the students in your class say that you are working for them or against them? What evidence would they use to support their claim.
How are you helpful?
What kind of listener are you?
Do you go out of your way to help them out?
In general in life there are those that work for you, work with you, and some who may actually work against you for any variety of reasons.
As an educator, you want to consider your role as one who works for your students--doing what you can to support their general welfare, learning experiences, and growth, and as you do your work, it's best to steer your ship in the direction of those who work for and with you too rather than those that work against you.
