Sounds like some fine 'sharp' pencilling going on with some rosters! From my experience the proper use of computer systems should put a stop to this practice. This will especially apply if trying to assign an illegal fdp, as any half-good system will be set-up so that you cannot do this.
Whilst on computer systems, of those that use one, how would you rate its usefulness in assisting you with your duties?
Something else that is noticeable is that as airlines have expanded the role of operations has changed to where you now have seperate ops & crewing staff. Over a period of time this has resulted in ops staff only knowing the ops functions & V.V. for crewing. Very few airlines have 'dual skilled' staff. This is not necessarily the fault of individuals not wishing to learn all aspects of OCC, but possibly company's not preparing to invest in ensuring that staff receive the correct training, which will offer more flexibility & understanding.
Also need to remember that some of the questionable decisions that are made have a large imput from those that like to ignore rules - COMMERCIAL
