The "no timesheet equals no check" policy works wonders.
You still have to pay them, but they get their check next week, not when they were expecting it.
One of the beauties of this policy is at you only have to do it once, everyone will hear about it and get their act together. That will be the last week that the paperwork is late.
That little trick brought several years of late paperwork to a screaching halt in one short week.
