The Maintenance Worker is the second type of staff in the original Zoo Tycoon. They clean rubbish from trash cans, repair damaged fences and tank filters, and sweep rubbish on the ground. They will also repair damaged restrooms. If named Bob V, all damaged fences will be repaired. If named "The Rock", almost all the building which the player has placed will degrade into rubble. This only happens in Dinosaur Digs.
