It has been going on for years and isn’t going to change because it goes through all levels of management. The pets get all of the benefits, even though they are often the least effective employees but they kiss @ss well.
Just do your basic job per your job description. (If you don’t have one ask for it saying you want to make sure you are covering your responsibilities.) Then do NOT bust your butt.
As far as training the pet, it isn’t your fault if they don’t understand your “explanations” and if they are such stellar employees they should be able to figure it out anyway.
Years ago I knew a guy who said it wasn’t worth all the effort to get an additional fraction of a percent in his raise so he decided to do the basic job and keep his mouth shut. Then he was promoted soon after! No lie!
Managers at Fidelity are some of the worst . . . And they know they don’t inspire employees or innovate in the work but they get their pay and play their games.
