Narrative:
Climbing out of stl, (captain leg) we were initially assigned 255 degrees and 3000 ft (MSL). Through 2100 ft MSL we completed the after takeoff checklist. We were then assigned a 220 degree heading (no altitude). I read back 220 degrees and told the captain 'I'm off 1.' as per SOP I called company with our times. Next thing I know 'check barometric altitude' sounds out. The altitude box said 3000 ft and the captain thought when we got the 220 degree heading, we also got 5000 ft (which is often the case). At 3500 ft he reduced power and nosed over. At the same instant, the controller said 'verify assigned altitude.' I said 3000 ft. No response. We leveled at 3000 ft and heard a 'thank you.' factors: this was a 14 hour duty day and was our last round trip. I was tired and so was the captain. I also missed the 1000 ft to go and 100 ft to go callouts as I was talking to company. Commuters are able to work you into the ground to the point of sheer exhaustion. If we complain, we go home without pay (and it is not much to begin with), so we can hardly afford to lose the trips.

Title: ALTDEV ON CLB. FO OFF RADIOS GIVING OUT TIMES TO COMPANY. ATC ASSIGNED NEW HDG, AND CAPT THOUGHT ALSO NEW ALT.
Narrative: CLBING OUT OF STL, (CAPT LEG) WE WERE INITIALLY ASSIGNED 255 DEGS AND 3000 FT (MSL). THROUGH 2100 FT MSL WE COMPLETED THE AFTER TKOF CHKLIST. WE WERE THEN ASSIGNED A 220 DEG HDG (NO ALT). I READ BACK 220 DEGS AND TOLD THE CAPT 'I'M OFF 1.' AS PER SOP I CALLED COMPANY WITH OUR TIMES. NEXT THING I KNOW 'CHK BAROMETRIC ALT' SOUNDS OUT. THE ALT BOX SAID 3000 FT AND THE CAPT THOUGHT WHEN WE GOT THE 220 DEG HDG, WE ALSO GOT 5000 FT (WHICH IS OFTEN THE CASE). AT 3500 FT HE REDUCED PWR AND NOSED OVER. AT THE SAME INSTANT, THE CTLR SAID 'VERIFY ASSIGNED ALT.' I SAID 3000 FT. NO RESPONSE. WE LEVELED AT 3000 FT AND HEARD A 'THANK YOU.' FACTORS: THIS WAS A 14 HR DUTY DAY AND WAS OUR LAST ROUND TRIP. I WAS TIRED AND SO WAS THE CAPT. I ALSO MISSED THE 1000 FT TO GO AND 100 FT TO GO CALLOUTS AS I WAS TALKING TO COMPANY. COMMUTERS ARE ABLE TO WORK YOU INTO THE GND TO THE POINT OF SHEER EXHAUSTION. IF WE COMPLAIN, WE GO HOME WITHOUT PAY (AND IT IS NOT MUCH TO BEGIN WITH), SO WE CAN HARDLY AFFORD TO LOSE THE TRIPS.
