Vantaggi
Shifts have pretty consistently been 8 hours, 11pm-7am. Only rarely been asked to start earlier or stay later and even then it wasn't much more than an hour, but your mileage may vary. I've seen other reception staff have to pull double shifts, turning an 8-hour into a 16-hour. Whether you work at a solo site or with a buddy, you're mostly on your own so if you like to get work done without someone looming over you the entire time then it's pretty good. It CAN be pretty chilled out if it's a good day and there's not much to do except sort linen trolleys and condiments and clean.
Svantaggi
BUT you can also have a lot of extra jobs sent your way by the day staff or you end up having to do things that they didn't/couldn't. There was a recent move to limit the amount of extra work you get per shift to just half an hour, but if you've already got a lot to do then even half an hour feels a bit much and there's even odds the extra work will take you more than 30 minutes anyway. Your job role is so vague that almost anything and everything falls under something you should or could reasonably do in the first place, so deciding with your hotel manager on what should be considered extra is a complete gamble. Either your HM will be fair and consider what tasks reasonably fall within your responsibility, or they'll just insist that there's no reason you can't do it so you might as well add it to the list. Considering it's night hours, the pay really isn't worth it. You can earn more for completing more e-learning, but it's pennies. There's actually decent opportunities for career progression, but there is nearly 0 opportunities for nights-related roles. So if you like working nights then you're pretty much expected to either stay in the same role at the same level forever or to advance to a different role such as duty manager or beyond (or even change to breakfast chef or something), but you'll have to ditch working nights.
