Appeal to the stick

We will strike so hard that we’ll surely be true!

The reader is warned about the unpleasant consequences of disagreeing with the proponent.

Examples
You’d better agree with the company’s new policy if you want to keep your job. (That policy is still in conflict with my contract clauses, hence opposing it doesn’t breach the contract but enforces it).
That subsidy is not a good option because by voting it you will provoke us into not supporting you for your reelection. (Well, I think that’s more a threat than an argument explaining why the subsidy is wrong).

To refute it
Identify both threat and proposition, and make clear that the threat is unrelated to the proposition being true or false.
