I worked in a company as an instructor and only this was the only thing written in my appointment letter "You will not approach Company's Customers (directly or indirectly) for employment. Even if a Customer approaches you for the same, you will not accept that under any circumstances. Company can take legal action against you in case of breach of this condition (even if discovered at a later date)" I am not joining any of my company customer as an full time employee but Can i work as freelance instructor for same customer for whom i delivered the trainings? Is it going to be legal? They are not paying my dues and they are saying they will send legal notice. Kindly suggest me on this.
