I’m the supervisor of a coffee shop on a college campus. We are run by a third party company. We have a sister store on campus that we work closely with. The supervisor at the other store recently told their employees that working with me would make them want to kill themselves. I went to the head of HR on our campus to handle the matter. They spoke with both of us separately about the issue and afterward I was told by HR “hopefully you both can work it out amongst yourselves”. I don’t feel like anything was actually done and I’m not sure where to go from here? Should I let it go or pursue the issue further?
