Dude?
Oh dear, 7700, you do indeed use the same terms that the Pinnacle guys did, just before they fell out of the sky from FL410...which clearly indicated the level of experience the regional guys have.
How very sad.
When you get to my level (25K hrs, the last 19K in command in heavy jet transports...and still flying 'em) of experience, 7700, you can tell me ALL about your problems.
Fatique?
Find another job.
The duty/flight time regulations have been used as a whipping boy for years by some malcontent pilots that many times simply fail to do the job for which they were hired.
Perhaps Subway is indeed more suited for these folks.
In short, find another job if you don't like the one you have now.
Rather basic, actually.
