Is it?
The last two times I was given a non-compete to sign (Colorado), I stood up and addressed the issues I saw with it.
The first one was reviewed by a co-worker's legal buddy. There was a lot of boilerplate, but there were also certain components that were totally unenforceable and unreasonable. A couple people signed it, but the majority of us refused. What is the employer going to do, fire everyone?
The last one was a completely reasonable non-compete. In my case, my work is fairly niche, and the number of people in Denver that are skilled is very few. If we decide to part ways, it could force me to either move or take up a new niche for the next 18 months or whatever. That part isn't so great as I don't want to move or necessarily take up a new niche. I spoke to the employer and we were both happy to agree to amend the contract to nullify the nastiest teeth.
Just because you are given a non-compete clause to sign doesn't mean you aren't allowed to discuss it in detail with your employer. They certainly should have the right to protect their business, and as an employee you understand that. You certainly should have the right to continue working after parting ways, and an employer will understand that.
If you talk to them about it, I'm sure you'll be surprised at the amount of flexibility they are willing to give.
