doctoring
Worked for them a couple of years ago. Had like 96.7 hours in the last 28 days, and was rostered a SSH and back. Called them the day before to remind them of that, and asked what they wanted to do. e.g.. land after 3.3 hours or not do it. The day I was operating I called crewing again and mentioned the problem again since they had not gotten back to me. I was told to go ahead and do the flight and they would "doctor" some of my previous flights so I would still be within limits. My answer of course was NO WAY !!
This is just one tiny example of the way things work.
