Don't delete old colleagues
While you may have moved on from your old job, it almost never makes sense to delete old colleagues, according to Matthew Jonas, president of TopFire Media, a Chicago-based digital marketing agency.
"Deleting old colleagues can be a sign that you are someone who is prone to burning professional bridges," Jonas says. "Unless there is a legitimate reason, (like) if the colleague is especially hostile toward you or might somehow sabotage your career through a post, I'd strongly discourage new employees from deleting old colleagues."
In fact, there's actually a lot of upside to keeping those connections because social media can be such a strong networking tool.
"You never know which one of your former colleagues will become your newest team member down the road," Jonas says.
