Company Policy; Human Factors
After working 5 consecutive days with a five leg day on day 4 with only a 10.5 hour rest period the night before and after just completing a 4 leg 9 hour day; I was junior manned. I did not feel alert or rested enough to accept the extension of my planned duty time; especially considering that it would have created a 7 day conflict with my next sequence.Cause - Staffing and Weather; ZZZ had long weather delays before my duty day had even started and was declared [non-normal operations]. The high winds and resulting weather made for a longer and more stressful day and I was very tired by the end. The bigger problem is the constant under staffing of the Captains on the Medium Transport aircraft in ZZZ. Junior manning should not be the only staffing solution; but it is! Every question above on this report is exasperated by the constant junior manning that we have experienced for the past X months.
Air carrier Captain reported fatigue due to long; consecutive days of flying and cited weather and staffing as contributing factors.
