@filmfreak75 @actuallyautistic firstly, boundaries. It's a red flag so limit your involvement to things that are less likely to produce actually toxic situations that affect you. Boundaries are promises to your future self about avoiding harm and don't actually need to be stated; boundaries are not rules for others, but signals for you to disengage.
Secondly, sincerity, "realness," a genuine desire to be a good colleague but not necessarily going with the flow to smooth over tension.
