I had a lot of Etls like this...
The best one, was in my 10th year I had a new ETL. After about 3 months of going out of my way trying to teach her things without her ever responding, she had to give my review (she didn't write it). During the review, she told me it felt like most days I was her boss, and I needed to pay more attention to the chain of command. I said "well I guess it's true they pay you the big bucks to be in charge."
As she gets to the pay portion, I see the wheels in her brain start turning as she calculates my hourly rate into a yearly one. She looked up at me and I had the biggest shit eating grin because I knew I made significantly more than her. She just handed me the review and left. Didn't speak to me for a week, not one word.
