Many times the employer doesn't care and might cut hours or eventually replace you altogether. I've heard this happen once or twice before, someone gave a mental health disclosure and found himself fired just weeks or months later. Because of his anxiety, they placed him in a room with minimal things to do and before you know it, they said we don't need your services anymore and he was fired. That's just one story I've heard about this type of thing, so be really careful and smart before you give them anything they could use against you. Reminds me of the saying, "Don't give anyone a stick to beat you with."
