The problem with that at scale is that some people can sneak in spite where there looks to be none and others hear spite where there is none.

That’s why you need a culture that allows people to listen to criticism without immediately feeling the need to be defensive. At work I have a few people I can be honest with and it’s very refreshing. I can tell them that I think some this isn’t right and they can tell me. If there is mutual respect and self confidence you can do that.
