A higher paid salary has negotiating power when being asked to work over time. Want me to stay late for a couple days no problem. Want me to work overtime for a couple weeks? Then I need to be paid at least straight time for every hour worked past 40.
So far I haven’t had any issues with this approach. They either pony up or suddenly it’s not that urgent. Have yet to be fired, but I don’t get asked to work overtime unless it’s truly needed now.
Normal practice is as follows for dignitaries let alone former presidents.
Secret Service man’s the venue itself. Local police man’s the perimeter. Every roof is not only secured but actually occupied. There’s an officer on every roof that is a concern.
Again, every roof physically has an officer on it. That’s how it’s handled for ambassadors, senators, and obviously leaders of a country.
