> Places I've worked that actually seem to have inclusion as a core value
I am not sure if you had implied it but that would align with my experience as well: places that tout diversity were the worst places to work (as someone who is seen as 'diverse') while the ones that treated everyone the same and had the expectation everyone pulls their weight.
I absolutely despise people treating me differently because of who / what I am rather than doing good work. I will take mildly inappropriate good-nature jokes over head pats every day of the week.
I love wildly beyond mild inappropriate jokes as they are a litmus test for a thinking person. The people that take things way too sensitive are a net drag and buzz kill for doing the grinding required. It goes both ways too. I love it when people are agressive with me. So, by freedom of association, cliques form and I have no problem with nepotism because the ultimate currency in life is trust.
