Hmmm...since when is QR legally bound to revised your salary. In fact, QR can revise your salary up or down how it see fit. Or worst cancel your employment contract, provided they comply with termination terms of your contract. QR is under no obligation that is outside realm of what is in the contract you signed. However you or the company can exercise the termination clause in your contract....
Termination
Either party shall have the right to terminate the employment, at any time, by giving the other party at least 90 days notice in writing or payment in lieu. Your right to terminate your employment with the company shall be subject to the provisions of your training bond (if any).
If QR doesn't cut your salary, particulary in part of the massive financial loss, be humble and thankful...if can :-) Now, I'm definitely not a QR cheerleader for the company, but keep in mind if/when they decided to revised your salary up or down, what will you do if it doesn't meet your satisfaction...
just food for thought!
