Unfortunately, that can come with some pretty unpleasant consequences. If you cut expensive 3rd party training then you could end up with:
A staff that is less then up to speed on current technologies and best practices which can lead to inefficiencies.
Poor staff morale.
So, how do you solve this problem without adding on new costs?
You can use the Whiteboard feature (whiteboard messaging) to have collaborative events where one staff member can educate others. A roundtable of your best minds teaching all of your staff, think of the benefits to your staff!
