We made our employees sign only a 4 lines non compete agreement when they start working 10 years ago. I redid a very professional non compete and confidentiality agreement. All 9 employees signed it, one employee doesn't want to sign it. No good reason given. I cannot even find the original paper he signed (again, only 4 lines).
Can I tell him if you don't sign you cannot work for me anymore or this may have negative legal consequences for me?
Can he argue this is a new request he didn't know when he got employed, or I owe him the money he will lose if i fire him (he is scheduled for few trips). or anything else
Basically is there negative consequences to make a cause and effect: if you don't sign this you cannot work for me anymore?
