The worse cases are when the Customer Rep gets a problem from a customer they have little power to resolve. When you are:
- logging tickets to a black hole of "higher tier" support with no communication back to you.
- "chasing them up for the customer" aka by putting notes in a ticket
...you feel powerless.
Then when the next call comes in from the customer you begin to think "Why am I even here. I can't do anything..."
Customer Support need to see their efforts make a difference, just like most people, in order to be motivated to do it again.
