> And finally having an employer that doesn't expect you to be in at 8am if you've been up all night is also very important, catching up on sleep is necessary to manage your balance and health. But given this freedom, I totally dig it. :)

Check the labour laws in your country, I'm pretty sure expecting people to be in at 8am after working on an incident during the night as part of your on-call is illegal.

In any normal country there are laws to ensure employees get enough rest every day.
