What do you think of me badmouthing a piercer while at work?
Do you work in the industry with the piercer?
How did you guess? Yes I work in the industry. I tell you one thing, he is the biggest prick I've ever met.
Badmouthing a coworker will cause tension and problems in the work environment. You should try to be professional at work Instead, you should focus on your work and not cause trouble.
It's fine, I don't care. I'm already fucking tired of this job.
It is expected that you treat coworkers with fairness and respect.
