I look at the same thing and think "Wow, these people are sad."
I've seen people like this first hand.
I worked for Sun Oil back in the 90's. There were 2 'young ladies' whose immediate supervisor went through a divorce and had found herself back in the dating scene. She would describe her dates the next day to these two young ladies. In. Detail.
They asked her to stop with the 'details', then asked her to stop with any 'info' about her social life all together when the first request fell flat. This too was ignored by their supervisor. They reported this to 'her' supervisor where it fell flat once again.
Long story short, the two sued and were awarded $11 million.
Needless to say, the rest of us in management went through some extensive 'sensitivity' retraining.
Since then, I have graduated to one of those people that have had to teach the classes to others. As serious as it all is on many levels, so often it is done with a wink and a nod.
I actually witnessed a company Vice President point at a humans resource director (in the middle of my training class) and say 'SO, calling (HER NAME) a prostitute would be wrong?' and then laugh.
I have also witnessed two 'white' supervisors, who were sitting and watching a 'black' male employee work (and he had been working for near 9 hours straight and busting his hump the whole time) if he would 'give them a song' like 'all their other workers do'. FYI- This was in South Carolina. The worst part was 'he' told me NOT to make an issue of it so he could keep his job.
One of the things that surprises me about the Twitter post you linked is this woman's extensive use of vulgarity. If a woman or a man spoke like to me, I would assume (whether it be wrong or right) that not much would or could offend them. Yet, it' the way she uses it that impresses upon me that she is exactly the type of person (again, I am assuming) that would lodge a complaint if someone she worked with used it in a conversation with her..IF that person were someone she didn't like, had a gripe or issue with, or had offended her with their own beliefs. I can almost hear her after the other person is reprimanded or what have you, saying 'I took care of their shit.'
