On-call

I hate on-call weeks. My husband still participates in the on-call rota at his work, - even though he IS the boss, and could justifiably get out of it - and I get a week of bad sleep, and have to field these weird calls about broken macerators, stuck lifts, no steam, fire alarms etc. He has a mobile, but sometimes it doesn't pick up the calls, and like just now, I have to ring the gym and leave strange messages, such as 'ring xxx at xx hospital, East7A are having problems with electrics'. What the receptionist thinks of the messages I'm not sure, but I sure get some funny looks when I go in... So, its Saturday morning, he's been on call for 32 hours, and he's had 8 calls already - I hope it calms down, otherwise I am not going to get much sleep this week, and that means a grumpy me, which is not good for my students.
