The The I think you will find you are not “stood up” your stand down is cancelled and you would be required to return to work as per your contract. If you didn’t wish to return to work then you would have a few options; a) take annual or long service leave, b) take LWOP, c) resign. The company can’t force you to do any of the above (they may suggest it’s in your best interest) but if you are not taking any of those options you will have to do what you are contractually obliged too or face disciplinary action. No conspiracy there just how they would see it.
