As a team lead, I had multiple times where I experienced problems with team members. I would always listen to everything that was being said for us to be able to understand and be able to come up with a resolution to make things better between us. If that didn't work, yes I would take it to the next chain of command. And hopefully at that point in time we would resolve it. Majority of the time, anytime I've ever had a problem with a team member, I like to communicate and understand where somebody is coming from and usually can resolve the situation before I get to the chain of command.
