Hi
In general staffing consultants are advised NOT to recruit candidates(So recruited through staffing consultants) from their client companies there by effectively restraining the staffing consultants from contacting any of existing employees.
In your case, the client has imposed a restrictive covenant on you which is in violation of Article19(G) of
constitution and by such restrictive covenant the client has effectively prevented you from approaching his employees.
Instead of inviting the client's anger and losing his business, you may resort to
a) Placing talent in companies engaged in business which do not compete with your existing client or
b) You are at liberty to place talent with industries which are competing with your client, if and only if any of the employee had approached you, on his own accord and will, either in response to your job posting in any employment portal, news paper advertisement etc.
3) Please note that No person can restrain you if any employee of a client company has responded to your job posting in a public domain(job portal, news paper ads etc).
Hope this information is useful.
