Yes, both WDW employees and UO employees receive complimentary passes to be used for their friends and families. These tickets are distributed on a quarterly basis. UO employee comp tickets are orange, while WDW comp passes are plain white.
Each ticket is registered to that particular employee. It is a requirement that tickets never be sold. A ticket can be found to be sold by an employee through our investigations department (through routine inspections of I-Drive ticket outlets, questions to guests coming in the front gates, etc). That ticket will be matched with the employee it was distributed to originally and that person's employment will be terminated immediately. Yes, both WDW and UO are THAT tough when it comes to comp tickets.
So, yes, these tickets do exist - but don't count on getting your hands on one.
