Q: Which of the following do most union leaders consider to be their primary responsibility above all others?
A. Union member wages
B. Union member health and safety
C. Union member benefits
D. Preservation of the union
This university was often criticized for its "conservative business school curriculum" in a "union town" ... so you can no doubt come up with what the professor considered to be the correct answer.
Pick D. ;-P
What I am trying to point out, however, is that the union is putatively a “partner/adversary” of the business, and anything the members do that harms the business (outside the bounds of the actual contract) is grounds for termination, especially in right-to-work states.
