To return to the original question. Does RYR issue a ticket free of charge to the 'employee'? In which case the system is working correctly as I believe they can legitimately do this provided the passenger is a genuine staff passenger on duty and they board as a passenger through the gate. Less clear if the passenger is an independent contractor. This would amount to handing out free tickets without payment of appropriate taxes.
Much more serious if the passenger merely breezes through the crew channel in uniform. This bypasses security and immigration requirements as well as evades the appropriate taxes.
