Are You Supposed To Send A Thank You E-mail When The Hr Send You An E-mail Saying:?

“I have forwarded your application to the department director”?

If Signed Papers As A Director &my Boss Is Saying It Was A Mistake &its Suppose To Be Associate,wht Can I Do?

i dont want to sign, is this legal? HR’s “mistake.” The only reason im annoyed is also bc i should be a director (based on qualification, experience, etc). can i take legal action for them demoting me for no reason? should i resign?
