Would depend on how much notice they got I guess. If the Company gives you the required notice, you will not have a choice.
@HTC, and therein lies the rub. The trick is remain contactable but unobtainable, at least that is until 12hrs before your scheduled departure.
Not easy to do, but certainly doable and in my case something I've practiced after falling foul when in similar circumstances I was "asked" to operate with about 5hrs notice. I asserted to the person what the OMA requirement was, which resulted in a delayed flight and a warning letter for yours truely, from that day to this I am contactable but unobtainable on ULR layovers and in complete compliance with the letter of the OMA wording.
