I am pretty sure that most workplaces are like this, however here it goes. Yesterday we were in a meeting, the big group of 20, and my half-boss brings up something that she and I have bumped heads about for literally 5 years. It is about art/crafts in our programs. She maintains that it is not 'skill building' to do crafts. I say that it needs to be well written and focused, but that it is a skill to cut and glue and get scotch tape for a 5 yo. So yesterday she announces that she is working with the art department to have them do a training with US about how to make arts/crafts skill building. She does need that training and conversation, I will probably be required to go however.
In any case despite our 5 years of butting heads she has never mentioned this to me outside the meeting where we are having another training added. This has happened many times, I spent a year butting heads over the scholarship policy and a $400 bill for a homeless family which made me generally look bad and the next year they massively expand the scholarship program, I talked about equity in afterschool programs, basically that the population of afterschool kids should reflect the school population in racial and socio-economic scales. 2 years later they made that a goal for everyone, again no talk at all with me.
I have only mentioned one of these one time to my boss (not half-boss) and the rest I don't know what to do with. Assume that I had some impact and let it go, wait until the next promotion opportunity and bring it up, or what I will likely do is just do my job and not expect much. (btw I don't think I would want a promotion anymore)
