lacking effort

[refiator]

Work your game. Lazy veterans are always a part of the game. If you don't feel that he/she work at their best, talk to your assignor and let them know your concerns. Do it in a non-threatening manner, with the thought that you are there to learn, but you didn't feel that this was a person who was there to help a younger official. It is likely that the assignor has heard this before and they need this info for future assignments for the both of you.
