In my employment contract (1 year, ends in March 2017), it says "Restrictive Covenant. At the expiration of employment with "Blah Blah" Physiotherapy, the Physiotherapist may not be involved in any way with a physiotherapy practice, at any time within a period of 6 months within a radius of twenty (20) kilometres from any place at which Clinics of "Blah Blah" Physiotherapy operate, without the express agreement of the Directors of "Blah Blah" Physiotherapy". Can this actually be enforced? I've been told different things about whether it can or not. Other Physios have left and joined other practices in the region. I wish to leave the practice but don't want to move towns.
