Human Factors
I awoke at XA:00 on Date and was called just a few hours later and told I was being placed back on rest; and given a XP:00 assignment. I don't understand how I'm supposed to be able to function; with less than 12 hours to adjust. I attempted to go to sleep at XJ:00 but laid awake till almost XM:00. I was awakened just after XM:00 when my phone received a text alert that my schedule had changed. I have no way to silence text alerts without also silencing all phone calls. I attempted to go back to sleep but was stressed that I would sleep through the call and could never fall back to sleep. Scheduling finally called me at XR:00; giving me absolute minimum notice to show; when I was forced to call in fatigued. I understand that this type of assignment is currently legal on paper; it shouldn't be; but I have to tell you that I flew transatlantic flights for 8 years and was never as fatigued as I have been on Reserve under this domestic FAR 117 rules. This is ridiculous. This is the second time in only 10 days that I was switched from day to night duty with less than 12 hours notice and after being awake for less than 5-6 hours. I want to make our system work so that the flights can be covered; but this current system is a system of 'gamesmanship'. No one is on the same team. Why don't we have a system where everyone wants the system to work to get the planes and passengers where they need to be? It just seems like it has become a war between the company and the union and not a great place to work anymore.
