Supermarket - If I was on Bakery, I'd start at 5:30am, work through until 3pm. If I was on Nightfill, I'd work either 6pm-12am or 9pm-3am. Not long ago I actually mixed those shifts together as they were short on staff, working 5:30am-3pm then 6pm-3am...home for 2 hours sleep then back in to do 5:30am-3pm. Absolute nightmare!
Pub - Usually split shifts. 9am-3pm, go home, come back and work 6pm-Close (which could be as late as 5am). Then back in at 9am. Being a barman was awesome though! Me and my boss once had 2 incredibly stunning women in the pub until 5am! They got there at 8pm! They just kept drinking and talking, so we called Lock In and the drinks just rolled on. I had to sleep behind the bar as I got too drunk to drive home:P
Factory (where I am now) - 2pm-12am. Not the latest shift in the world, but I'm not really enjoying the late hours. My entire social life takes place when mates/girls finish work (usually around 5-5:30pm). When they're all out of work and socialising, I'm just settling into the rest of my 10-hour shift.
I'm much more of a night owl than an early bird, but as far as my life is concerned, early mornings are definitely better. I've just applied for a job which will be 6am-2:30pm...and I'm hoping I get it, so I can start a bi-modal sleep cycle again (like I always used too).
