If this is about factory work, yes, training is necessary.

If this is about software development it's not clear to me what sort of training we are talking about. I've had to train myself at every job, that's part of what I do. I can't imagine how training would work. Classes in some programming language perhaps? It's much faster for me just to pick up the syntax of a language over the weekend and then fill in the blanks on toy projects or while doing maintenance.
