My right to free speech is seriously curtailed while I'm at work. I could go to the mall and use abusive language or bad-mouth my company's products. Can't do that at work and remain employed. It's that simple.

And if your employer tells you to kill another employee, do you obey that illegal order and do so?

Not analagous. When I agreed to work for my employer I agreed to follow rules that are more restrictive than what I can do outside of work. That's a legal contract. Telling me to do something illegal is outside the bounds of the contract. I don't think you can even include something illegal in a valid contract.
