Before anyone says that J* guys should simply "work to rule" if it can be determined that pilots are working to rule then they can be charged and if it cannot then the company would not know nor therefore care and you are simply left with a bunch of bitter and twisted pilots throwing on a bit too much fuel for Mum and the kids at the expense of the environment without the company being any the wiser.
The Captain can elect to do all the takeoff & landings if he/she determines the conditions aren't suitable for a low time jet f/o.
Unfortnunately ILS, takeoff & landing recency suffers. But operational safety is the Captains main priority.
