ought in postindustrial society, but the notion of training is not pre
cisely defined. It is not just the acquisition of knowledge or techniq
ues, it is also a structural element in an individual's overall activi
ty. The notion of work is equally unclear, and is often subsumed into
that of employment. The passage from training to work is undergoing ma
jor change and the distinction between the two is blurring, which affe
cts the nature of the employment contract and casts new light on the l
egal recognition of vocational skills.
