I'm going to post an angry rant about my work on facebook after I had a really bad day
Why do you need to air out your work problems like that?
I just want to complain to my friends about what kind of shitty job I have. I hate it.
You should't air your hatred of work on social media. People don't want to hear about it and you might get in trouble with your boss.
Are you my boss?
I'm not your boss, but I just want to say that you might be giving yourself a bad impression to your employers like this. How would others on social media, and the workers who see it, feel you ranting in public? Perhaps do it in private with your friend, so no one gets distrubed.
