Totally agree with TheBrit. Would add that many labour laws are in place to protect workers who have significantly less bargaining power than employers. Allowing employers to waive these protections if the worker "agrees" undermines the rationale for the law. Some are in a place in life where they are willing to live in a kitchen, but in order to maintain and even enhance rights for all employees minimum standards that cannot be waived need to be set. In the end it isn't just the individual employee who is okay living in the kitchen that is effected. If one employer does it, then someone else will and suddenly the exception becomes the rule and to get a job helpers are stuck accepting sub-legal conditions that the law was designed to prevent.
