I have a 3 month notice period in my contract and the usual restrictive covenants that you would expect of a middle manager, however after 6 months into my 1.5 years with the company they introduced further covenants for all middle managers up, which stated that i could not work for a competitor for at least 6 months.

I have been offered another job with a competitor and whilst i have no trade secrets, customer or sensitive information that i could misuse, how enforcable is the statement that i cannot work for a competitor.
