followed with ‘I wasn’t aware is so important to you. I didn’t want to insult you and if you felt so, I apologize. The word fuck is one I use very often, but I’ll try to control myself around you’
Note I didn’t insult the coworker (no fuck you or fuck off), but simply said ‘fuck’ out loud due to a job error.
You don’t have to say anything, just change the behavior around them. If you’re required to apologize, “I’m sorry. I’ll work on that.” should suffice
Not everything is about what we’re “required” to do. If op wants to apologize, why try and talk them out of it?
I agree. Id prefer to just address it openly and directly.
