Definitely no sarcasm! I like to promote a debate where possible. This "hours" thing is too rigid....it should encompass common sense and flexibility. Some days an hour and a half on a continuously-busy sector [especially Terminal Control] can be a killer.....on other days two hours can be a breeze. This'll make you laugh, you too "Brian"........when I was at Benbecula it was a one-man station and I did five and a half days plus callouts [overtime slips to prove it]......now it has several controllers to handle the four planes a day [a lot fewer than I had]. I went back for a visit a couple of years ago; one controller spoke to the inbound aircraft and handed over to the other controller who did the outbound leg......this'll double you up with mirth.....the inbound acknowledged the ATIS, and the controller who had only that one aircraft advised the pilot that the information had changed and told him to get the new one.
Back to the point, which is.....one size does NOT fit all.
