Narrative:

During climb out from tup airport we overshot our assigned altitude by 500 ft. Contributing factors are crew fatigue due to long duty days and our company has a waiver for sterile cockpit below 10000 ft and not in cruise. To explain fatigue our duty day was 13.6 hours and 8.3 hours of flying time. For the week we had 50.8 duty in 5 days and 27.1 flight time in the same period. This is in the jetstream 31 which has 'no' autoplt and 'no' altitude alert system. A severe WX system had just cleared our section of the country with tornadoes, hail, thunderstorms, and severe winds during that wkend. Per our G.O.M. We can make calls to company in a sterile cockpit environment along with monitoring company frequencys. This takes your attention away from duties at hand and I think that should be changed.

PER OUR G.O.M. WE CAN MAKE CALLS TO COMPANY IN A STERILE COCKPIT ENVIRONMENT ALONG WITH MONITORING COMPANY FREQS. THIS TAKES YOUR ATTN AWAY FROM DUTIES AT HAND AND I THINK THAT SHOULD BE CHANGED.
