Yeah, if it’s a safety issue, then it needs to be documented and sent up the chain. Attitude can’t be disciplined out, but safety violations can. Let things play out with your command, but if it is a consistent serious offense and not a minor thing here or there, then you should push it as far as your able, and encourage your team to do the same. Safety is paramount, the job is already dangerous enough. If not and you feel that it is unsafe to have people dive under his command, encourage your guys to voice that opinion, if that is how they feel, and you should as well.
