I won’t burn them theatrically but I’ll let ones I don’t particularly want to keep around quietly just fall into disuse. The bridge is still there but Id have no intention to reaching out across it any time soon. Once in a while people do change over time, sometimes they mellow out or realize they fucked up. A disused bridge is easier just easier to deal with than a burned bridge.

Good bridges aren’t about pretending things are sweet and dandy, good bridges are honest communication and connection, burning them means passing people off on the other end and pissed people are more likely to retaliate. People who feel mostly neutral or a bit annoyed don’t retaliate.

When you leave, wherever you’re working be honest but professional. Say you felt your coworkers didn’t value your time and work you did and at times their unprofessional behavior impacted your ability to work. Don’t name names, don’t finger point, but be honest with what dissatisfied you. If you have an at least neutral professional relationship with your manager maybe they could be a reference for future employers.
