how long will it be before the powers that be in this case EASA pull there operators License
Very shortly after the Administrator or worse, the Liquidator, is brought in I would imagine
If a company can't pay its employees, it won't be paying its creditors either and some, or all of them, will comment legal action for payment which will likely result in the company being put into Administration.
Alternatively, there is nothing to stop the employees doing this and they may be better off since under Insolvency Act, employees have a right to be paid over and above trade creditors. But this is not something to commence without very careful consideration as it may result in the clsong of the business.
