No matter where you go, there will always be that someone that makes things difficult.
Every job I have had, there was always "that person" that just makes the whole environment toxic.
Some cases you either stand up and stand out or be like the rest of the crowd to blend in,
There's as I always say, pick your battles, thinking the grass is greener on the other side is never the right move, once you put your mind set that you are in control of you, and not let anything or anyone throw you off your game is key.
Once they piss you off you are no longer in control, they are.
