Have a coworker in a different department that has been difficult since she started. She has sent me emails as if I work for her. I’m literally doing her work on a project because and I quote “you know what you’re doing.” For months I’ve reminded her she has a very simple report due. She claims she is so busy. Well lo and behold the other company sent an email threatening to no longer pay us as her report is 3 months late. I sent her an email and basically told her hey submit your report and here’s an idea for tracking when these reports are due. I cc’d my boss and her boss. My boss called me to tell me I needed to be nicer to her and call and apologize. Next time she’s late and the other company has to threaten us again, I’m not notifying her. She can be the reason we thousands of dollars.
