Any concerns about posting this on a public forum and not trying to remain anonymous?
I probably wouldn’t do it.
Not just in regards to your current employer but also considering how future employers might feel about you sharing intimate facts about the company in a rather sarcastic tone. There are always multiple sides to a story.
That being said, your situation sounds frustrating. However, if you can’t live with it and have other options, leave.
Your chances of changing this place fundamentally, I’d say, are rather slim.
