If CX wants to go "onshore", let them. The last thing they want is to be subject to the respective labour laws of local jurisdictions. Just wait to those new Dads ask for their 6 months paternity leave. Or better yet, imagine trying to offer a take it or be fired COS in Canada, especially now in BC. The Supreme Court here recently shot that down in reference to the HEU contracts a few years ago. Moreover, I'm rather certain that an employer is bound to meet their obligations in respect to the various taxes and levies and are not allowed to pass them on to the employee.
A quick call to your local government agency will clear that up.
