Well done, Jenny - youve made 'Owing Bucks' live up to his contractual obligations! I reckon he had no choice but to cough up the bucks owed you because you had been employed legally by his ropey company.
But how many other FT's who have worked for him have lost out through not being legally employed. Unlike you, they had no way to force him to honour the terms of their contracts with him!
Ft's working on L visas ofr F visas in china run the risk of being cheated by unscrupulous employers like 'Buckie'!
