Imagine that the given text is a social media post, and you have to write the title of the post, so the users can decide to read the main text or not.
Input: Obligatory on mobile and further apologies for crappy writing. I don't make long winded internet posts often and I tend to ramble and jump around.

I'm a young guy. I have been saying "what's up" as both a greeting and a colloquialism for "what's going on" for a few years now. To be clear I don't say"whassup." That is totally different and I recognize the difference. It has become a part of my speech patterns and basically automatic. My Assistant boss (not assistant to me but assistant to the boss who is another person entirely) has berated me a few times for saying "what's up" to both her and other people for a few different reasons. She has cited A) That it is a respect issue B) It offends her C) If a third party overhears it can become an issue because they don't know what is being discussed (I don't understand that at all) and D) It is unprofessional. I have never heard anyone else have a problem with this phrase in my life. My coworker thinks that she is just out to get me because she doesn't like me. I am trying to not do it but like I said before when someone addresses me it is my instinctual response and when I do accidentally forget to stop and think about what I am saying so I don't say "what's up" she gets upset even when I apologize immediately afterward. The boss doesn't seem to personally care but he is letting here just take the reins for this. I am going to continue trying to avoid it but I wanted to ask you random internet strangers your opinions. AITA or is my assistant boss just picking at nothing?
