My boyfriend's a manager at restaurant. it's a pretty social and his employees/coworkers drink quite a bit... and quite frankly don't seem all that mature. 

He doesn't always speak highly of them but lately I feel like he's lowered his own standards of behaviour, in a way that lines up more with how his coworkers act. they can be a lot of drama and watching him get more into the crowd is worrying. I'm finding it unattractive. We've been seriously dating for about 5 months now... he was newer to this job when we first started. 

I'm not sure what's the best way to go about this conversation without feeling like I'm attacking him. I don't just want to just drop this relationship... I also don't want him to get more and more like his employees/coworkers. He is really stressed, do I have a right to talk to him about his coping mechanisms and my concerns?

boyfriend works with young-ish partiers, he's been drinking more and hanging out with them while getting a bit more sloppy with professional distance. DO I have the right to talk to him about it? how?

How do I tell my boyfriend that I don't want him to become a more passive asshole?
