Why would you accept to get into a job with unpaid overtime?
If the money is right, then I'll listen. But even then I have my limits...
Maybe it's my experience, but I just turn down offers if I even get a whiff of pressure to, essentially, work for free.
Anymore, that's what I do as well. I'll turn 60 this Friday, and I really don't feel the need to kill myself anymore.
But here in the States, you work at the pleasure of your employer. That means free OT if you will put up with it. I won't.
Where companies have really screwed up, and apparently haven't figured it out yet, is that now that there are no pensions to speak of (with the exception of Federal government and Military jobs), there is no reason to put 30 years in one place. Why would you?
They have effectively turned engineering into high-skilled construction jobs. And as any construction worker will tell you, "I was looking for a job when I found this one..."
