TWR CTLR AT IAD WORKED A 2 HR PERIOD DURING THE LATE NIGHT SHIFT WITHOUT A SECOND CTLR IN THE TWR CAB.

Narrative

I WAS FORCED TO WORK THE LATE NIGHT SHIFT AT IAD TWR BY MYSELF FOR 2 HRS. I ASKED THE SUPVR IF THEY HAD CALLED ANYONE IN ON OVERTIME TO COVER THE ENTIRE SHIFT. HE REPLIED THAT THE OPS MGR HAD DECIDED TO GIVE THE PERSON THAT WAS WORKING THE PREVIOUS SHIFT 2 HRS OF OVERTIME ON THE BACK SIDE OF THEIR SHIFT TO COVER UNTIL XA00. THEY ALSO GAVE THE PERSON THAT WAS ASSIGNED A LATER SHIFT 2 HRS OF OVERTIME TO COME IN AT XC00. THIS THEN FORCED ME TO WORK THE LATE NIGHT SHIFT AT IAD BY MYSELF. I FELT THAT THIS WAS A CRAZY THING TO HAVE ONLY 1 PERSON WORKING IN THE TWR. I MEAN THIS IN IAD TWR. ONE OF THE 5 BUSIEST ARPTS IN THE COUNTRY AND IAD MGMNT IS TRYING TO SAVE 2 HRS OF OVERTIME ON A SHIFT. THE LATE NIGHT SHIFT IS SLOWER THAN THE OTHERS BY FAR. THOUGH IF I HAD TO GUESS; I PROBABLY WORKED 6 ACR'S; 10 AIR TAXIES AND 3 OR 4 GA ACFT DURING THOSE 2 HRS. I AM OFTEN WORKING 4 OR 5 ACFT AT ONE TIME. I HAVE MAINT ACFT THAT ARE UNFAMILIAR WITH THE ARPT TAXIING THAT OFTEN MAKE WRONG TURNS. I HAVE DEPS TAXIING OUT. ARRS INBOUND. ISSUING FLT PLANS. THE ARPT IS OPENING AND CLOSING THE RWYS ON EVERY LATE NIGHT SHIFT. REROUTING DEPS FLT PLANS. NOT TO MENTION THE ADMINISTRATIVE DUTIES LIKE COUNTING FLT STRIPS BY HAND.
