Yep, that was my point if I didn't make that clear. If you want a job bad enough you'll put up with their requirements knowing that you'll have to change your habits to adhere to their policies.Lots of people work for companies that require security clearance. If they are naive enough to think the checks stop after they get the clearance, that's their mistake. If you regularly hang out somewhere at 4.30 am, assume that eventually somebody will check up on who you are hanging out with, and they don't need to ask your permission first. You signed away your rights to privacy for the rest of your life when you applied for the initial security check.
That's not just a hypothetical assumption - but I would have to shoot myself if I put any evidence of specific cases on an internet forum, of course
If the job isn't desirable, and the restrictions are too high, you wont get the people who add value.
