re: New Employee Contract , Non-Compete 3 Years

Is this for a current job and current employer wants you to sign, or are you taking a new job and the new employer wants you to sign?

Generally speaking...

If current employer, then they need to give you something (consideration) in exchange for your signature. This could be a bonus, raise, etc. Continued employment by most likely itself isn't sufficient for the contract to be valid.

If taking a new job, then the job itself is consideration and the new employer doesn't have to give you anything else.
