Well presumably, if Sex Workers have a Tax ID I wonder if they'll be given a 'Job Description' too? That would make a 'fun' reading. Will they have cock, sorry, 'clock in', do shift rota etc.?
Seriously though, would the government actually make sure these workers are taken care of with things like medical care and proper protection? What kind of 'books' are the workers going to keep for income assessment? Or is it just going to be 'give us tax and carry on as usual'.
