I have spent more than a decade watching the same pattern happen to brilliant employees. They come to me convinced something is wrong with them. It is not. What is wrong is the system around them. Once I show them that, everything changes.
What is happening to you is not random. It follows a pattern that employment attorneys recognize. Once you see it, you stop reacting and start responding.
You are not too emotional, too sensitive, or too difficult. Your instincts are correct. The same awareness that is keeping you up at night is the power we redirect and use to build your case.
You do not have to quit or wait to be fired without severance pay. The law has tools most people do not know about, and you can use them to protect your peace and your pay.
