A non-solicitation clause (or non-dealing clause) aims to prevent you from contacting or soliciting clients and customers (and even acepting work from such client/customers) of your former employer, and potentially even poaching existing employees of your former employer.
As with non-compete clauses, a non-solicitation or non-dealing clause will only enforceable if it is reasonable and protects a legitimate interest of the employer. A non-solicitation or non-dealing clause which is too broad or which applies for too long may be struck down (e.g. it applies to apply to customers and clients with whom you have had no prior contact). We can help you work out if you are bound by your non-solicitation or non-dealing clause, or how you can avoid the effect of this clause.
