Please help with a prayer to help let go of anger and resentment against my coworkers?

Are there any prayers out there that help with dealing with resentment and anger towards my coworkers. I am dealing with the situation(which is long but has to do with them not doing their work on purpose out of spite) with as much loving kindness as I can but inside i am angry and feel like they need a lesson shown. I'm all alone nobody is helping me, I have no support. There is one co worker who hates me and will do anything to make me mad, because i am in charge...I need to let go of resentment and anger towards this whole situation. I work with mean people and the anger i'm feeling is interferring with me living my life in a peaceful way.
