we call this sort of thing: PENCIL WHIPPING in the USA.
Eastern Airlines (rip) had a problem with pencil whipping during the really bad days after most of the Real eastern people had left.
Does this stuff really happen? I have seen it done at much smaller outfits.
I wrote something up in a logbook (mx log) and came back the next day to find that page had been removed from the log book!
When I asked about it, I found out the answer and resigned.
