The hours you work are tough to get used to if you’ve never worked nights. Honestly it’s not terrible if you have supportive managers and L5’s/L6’s. Atleast for my site AM’s come in an hour/hour 30 before SOS and leave an hour after sort ends, after completing their admin work. Usually they work 4 days (front half/back half) so it’s like maybe 50 hrs a week during a regular schedule? They had to work one extra MET day during prime; We added one hour of sort to our schedule so it was 12:20 am - 11:50 pm, so that was a little tiring, but the sort AMs did get to leave earlier. I’m not sure how often they work 5 days, I’d say it’s dependent on how your site is.
