I don't think there is any question of being paid. It's going to be a matter of when.
If the Company is in Administration now, I believe it is unlikely that your friend will receive her pay in the normal way. Correct me if I am wrong, but the bank would most likely process payments, in respect of salary to be paid by Wednesday, today.
She is going to have to wait and see what the Administrators plans are.
There are exit routes from Administration which generally involve either shutting the Company down by way of liquidation, in which case your friend will claim her pay plus any unpaid Holiday pay from Redundancy Payments, who will also process Redundancy and Notice pay entitlements. Or
The other alternatives may be a re-structuring it in such a way that it can 'trade out' of the current position and effectively write off debts by way of a Company Voluntary Arrangement. It depends how the re-structuring works - the Company may lay off staff to cut overheads. Those laid off may possibly be offered voluntary redundancy packages paid by the Company or they may be laid off by way of compulsory redundancy in which case they would claim as in liquidation above. Those retained, it should be business as usual, though the pay may not necessarily hit the bank at the time expected.
Another possibilty is a buyer for the Company is found. If that happens it is by no means guaranteed that the employee contracts will be taken on by the new Company. If they aren't then the claim process as in liquidation would be adopted. If they do take employees on then Transfer of Undertakings regulations will apply - basically the new company adopts the contract. Continuity of employent would be preserved and she will be paid by the new employer.
Until the Administrator's Report is prepared, unless the meeting she has been advised of explains her position, it's unfortunately a matter of waiting.
Tell it like it is.
