Narrative:

On commencing my 6TH day on duty, I left the hotel at XA40 to arrive in smf operations where I learned that I had been assigned additional flying upon arrival in den, which increased my duty day from 3.5 hours to 10.5 hours. Every layover during this long workweek has been the minimum 9 hours at the hotel with the exception of one which was 7.3 hours due to my agreeing to operational integrity to get the morning flight out on time. The entire week has involved flying into WX and included a massive delay for WX into destination. Due to fatigue, I felt that it would be unsafe to continue flying after arriving in den and notified the crew desk.
