They get paid and they push code but they seem to think that’s the be all and end all of the relationship. It would be like living with a partner who takes out the bins and cooks every other night but never gives you a birthday card and constantly complains about your behaviour.
I don’t think there’s anything at all wrong with wanting to have good social relationships between staff because the flip side is that every Eeyore, loner, and whiner chips away at morale bit by bit until they are the only people left.
How have you rewarded camaraderie, positive attitude, leadership, and goodwill today?
