This is essential for those who work for a consulting organization.
Time spent sending you to training is time not spent billing you to a client. Plus, not only does the consulting company lose the income for your time, they have to pay to train you. They don't like to do that, period.
Customers hire you because of what you know, not for how well you learn.
This means that, over time, you will only get hired to do things you already know how to do - until no one wants to hire consultants for that skill anymore.
In effect, your skills go stale and you end up unemployed.
Planning to keep your skills current is essential for long term employability. It's much to important to trust this will be done by your employer for your benefit!
Incidentally, if you write articles and publish them in user group publications, plus start presenting at local user groups, you'll get sales leads you can pass onto the sales people. Try to get accepted to present at software conferences. Your boss will be much more willing to send you - it's a marketing expense not a training expense. Marketing expenses are investments by the company for itself.
Even if you're not a consultant, getting accepted to present at a conference doubles the chances that your management will send you to the conference.
