I have to say that I have always been willing to help others out unless I have a crisis of my own. Believe me, I have worked with many lazy "coworkers". In the past I have always "killed them with kindness" by either answering call bells, starting IVs, etc and then I let them know that I have done this for them. After a few times of me helping them without being asked, they will normally reciprocate. Of course, there are always a few that won't budge.
