I haven't been modded troll in, like 40 hours, so I was feeling left out. Anyway...
You're employer is under no requirement to pay for training unless they have asked you to job which requires that training and they hired you knowing that you did not have those skills. Some companies provide training as a benefit - allowing you to increase your skill level in your field or even a related one on their dime because they feel that developing in house expertise is valuable and will pay dividends. If your company identifies a need for a skill which you do not have, I would expect them to either hire someone else or offer to send you to training.
In any case where you bring a possibility for training, your manager (we hope, though sometimes it's faceless management or HR) will look to see if it increases your ability to perform work and provide additional value to the company. That gets played against the budget, the path your employer has for you within the organization, your value to the organization, and your overall marketability.
As a business owner, I can tell you that training is wildly expensive. As a former employee, I can tell you that conferences - on the whole - are wasted time and money for the employer. Training is a toss up unless it's directly related to your work or the work the company would like to go after or compete for. If you ever think training is cheap, take the cost of the class, the cost of transportation, the cost of lodging, the cost of per diem then add to it about $500 in internal time processing all the requests and approvals, then take your hourly rate times the number of hours you'll miss work and multiply it by 2.5. THAT'S the cost to the company. And that's why not all training is approved. A $250 conference for half a week can easily hit $5,000 in costs to the company.
I'm not saying that training is bad, or that companies can't find value in training, or that this particular company is good or bad. Merely pointing out that the cost of training is far higher than most employees ever realize.
