I find it is usually possible to convince your employer to give you time to study up - whether this is extra time tacked onto a project because "I need to learn the framework", or actual formal training.

I think not making your employer pay a fair share of your training is like being one of those people who stay 4 hours extra when their project isn't late. People do it through a mixture of anxiety, peer pressure, and possibly not liking their children all that much.

To me, it is your responsibility to learn the tech you want to use in your next job, but it is fair to ask the company to pay for new skills you need for them.

From the companies perspective, it is worth spending the money up front so that you don't mess up a project by not really knowing what you are doing.
