I've never been asked to sign an updated contract for a job.

I've had to sign sort of sub-contracts, e.g., during option awards. I think my main employment contract might have been updated once, when the employer I worked for was acquired, but it was a while ago so I could be mistaken.

I had an employer tie a forced arbitration clause to a stock option refresh.
