How many of you work hours other than the standard M-F, 9-5 or 8-4 out the door?

M-F 10 to 6, but also extra hours whenever needed. So sometimes I'll get 12 or 14 hour days or work a weekend. Or I'll get 60 to 70 hour weeks for a couple months but those are pretty rare lately. Done them before though. Salary, so no overtime when it happens.
