I simply asked where I might find the "the HKG Govt guidelines of after 10 years service 1 month for every year served plus 3 months." I have never seen such guidelines from the HK Government.
Moreover "Even a domestic worker with more than 10 years with one employer gets better terms." Well no. I have in my hand the mandatory Employment Contract for Domestic Helpers, and, apart from a flight back home, FDHs are entitled simply to the legal minimum as prescribed by law. (Employment Ordinance, Cap.57) In their case of course it is 2/3 * monthly salary per year of service (since they don't reach the cap of $15,000).
Frankly I am tending to concur with the view of others here that you basically just spout crap.
