While we are without question overworked and underpaid I fail to see what difference it matters weather it is the right or left seat. Working right up to the max is not safe and you should know that. I don't know what rag-tag airline you are with since the word on the street seems to say you are not EMirates but 12 days a month working should be the max for long haul. By the way I am out of time for the year and only worked 5 days last month and it was such a relief! I am recharged and a new man.
That does not bode well for my friend here at Emirates who flew 1125 hours last year (not inlcuding the factoring) and then recieved as a belated Christmas gift 6 midnight sim supports in a row. If that is not a recipe for fatigue please tell me what is.
