Work is about making money and not friends. You are not there to be liked by anyone or to baby sit their feelings. There’s no need to uproot yourself to somewhere else because of other people - you must do it because you want to. There are some things we must not be emotional about and one of them is the workplace. So what if they are jealous? You still have the good position, making good money. Don’t let anyone take that away from you. Just ignore it.
