Maybe it was a 3-month or 6-month TRIAL period. After you passed it then you got the medical insurance, the vacation and sick leave and whatever other benefits were offered to full-time employees.
WHY NOT MAKE A PRESIDENT TRIAL PERIOD for awhile? I know it would be very complicated and expensive to boot him/her out and get a new one to trial period. But not nearly as expensive as being stuck with a corrupt treasonous lying nutjob crackpot for 4 years. Whatcha think?
