So presumably they are trying to get contracts elsewhere then? Nobody else willing to given them a contract? Not doing a good job of exciting any prospective employer are they on account of them appearing to be shit at their jobs and not deserving a contract here or anywhere else. How about some professional pride?
If they really were to say," why would I bother, I have no contract" then they would be parasitic scum.
But I doubt they would ever say, haven't said it and that and are indeed trying their best..... because they are professionals and don't think like someone stacking shelves at Tesco hopefully.
