Jill, I believe non-competes vary from state to state in how well they old up so you should look into this.
That said, I would be very interested to know what an attorney says about this even if you are in a “good state”. I dont think you can legally prevent someone – who is not a full time employee – from seeking work outside of your establishment.
I dont think you can control what they do in their private time. What happens after they sign it if they discover the job doesn’t pay enough for them enough to earn a living?
I’m no lawyer but even if the trainer did sign it, I dont think it would hold up esp for a part time employee.
Unless you are paying the trainer a living wage in exchange for this long time commitment, I wouldn’t sign it.
just my 2 cents
