Most don’t, I’m wondering if they should.
As hinted in my previous comment, I don't think they can and I am also not convinced that it would be beneficial to them if they could.
They need good engineers. That is achieved through hiring and compensation policies. Then, it is also beneficial to retain and keep engineers up-to-date through a level of training as needed.
the less effort exerted globally by the workers the less expectations will be placed on them by managers. God forbid people find their meaning outside of drudgery on their lords fief.
