I never get to turn the power off.To tell you the truth I am geting pretty sick of it too.Of course I work for a hospital.When I am working for myself I de-energize things much more frequently.Not paying a guy for "manadatory traing" is b.s.If you offer shop training as a benefit not a requirement that is totally different.My thoughts on call backs is sometimes poo poo happens.I am sure most employers can tell there good electricians from there bad ones.Big John take a quick look at some of the employee's and see if they appear happy.That will be a good indication for ya or you could try one of staffing companies to get a fell for some of the contractors.Good Luck
