put (one's) head on the block
To assume or expose oneself to some risk, danger, or responsibility; to imperil oneself or put oneself in harm's way; to risk damaging one's reputation as the result of doing something. Look, I'm putting my head on the block for you here. I could get fired if they find out what we're up to! You have to take some risks to be successful in business and in life, but don't put your head on the block for no good reason.
