Narrative:

Working the late night shift on day 5 of work week. Extremely fatigued all night; but mostly during this last 90 mins of my shift. Working 3 approach controls; 2 low altitude en route sectors and 2 high altitude sectors. Basically; I had the airspace from the surface to infinity. Several 'red-eye' aircraft inbound to dtw and cyyz. Several departure aircraft off of lan; mbs; fnt. Aircraft departing fnt and mbs required clearance delivery of the flight plan information (heads down time). Had 20 aircraft climbing; descending and transiting the sector for 40 mins. During a normal day or evening shift; the sectors would have been decombined with 3-4 controllers. This is extremely unsafe working these position combined -- anytime -- especially during the time a controller is most fatigued. The management does not staff this shift appropriately to accommodate this predictable traffic flow. It is like this every morning; and this is getting ridiculous. Solution: staff the shift with 3 fresh controllers beginning at XF00. This would ensure tired; fatigued controllers working their last hour of duty; possibly on the last hour of work week; from making potentially fatal decisions. Help! We need to have this better staffed or curtail services.

Title: ZOB CTLR EXPRESSED CONCERN ABOUT SECTOR WORKLOAD ON MID SHIFTS; CLAIMING SECTOR WOULD HAVE BEEN DE-COMBINED DURING OTHER PERIODS.

Narrative: WORKING THE LATE NIGHT SHIFT ON DAY 5 OF WORK WK. EXTREMELY FATIGUED ALL NIGHT; BUT MOSTLY DURING THIS LAST 90 MINS OF MY SHIFT. WORKING 3 APCH CTLS; 2 LOW ALT ENRTE SECTORS AND 2 HIGH ALT SECTORS. BASICALLY; I HAD THE AIRSPACE FROM THE SURFACE TO INFINITY. SEVERAL 'RED-EYE' ACFT INBOUND TO DTW AND CYYZ. SEVERAL DEP ACFT OFF OF LAN; MBS; FNT. ACFT DEPARTING FNT AND MBS REQUIRED CLRNC DELIVERY OF THE FLT PLAN INFO (HEADS DOWN TIME). HAD 20 ACFT CLBING; DSNDING AND TRANSITING THE SECTOR FOR 40 MINS. DURING A NORMAL DAY OR EVENING SHIFT; THE SECTORS WOULD HAVE BEEN DECOMBINED WITH 3-4 CTLRS. THIS IS EXTREMELY UNSAFE WORKING THESE POS COMBINED -- ANYTIME -- ESPECIALLY DURING THE TIME A CTLR IS MOST FATIGUED. THE MGMNT DOES NOT STAFF THIS SHIFT APPROPRIATELY TO ACCOMMODATE THIS PREDICTABLE TFC FLOW. IT IS LIKE THIS EVERY MORNING; AND THIS IS GETTING RIDICULOUS. SOLUTION: STAFF THE SHIFT WITH 3 FRESH CTLRS BEGINNING AT XF00. THIS WOULD ENSURE TIRED; FATIGUED CTLRS WORKING THEIR LAST HR OF DUTY; POSSIBLY ON THE LAST HR OF WORK WK; FROM MAKING POTENTIALLY FATAL DECISIONS. HELP! WE NEED TO HAVE THIS BETTER STAFFED OR CURTAIL SVCS.
