If there is someone in your company, who is in a position that management can not show is making the company money, then the problem is that said person should not be in the company, or optionally you have incompetent managment.
You may think that most IT staff in a non-technological company is not making money, but someone along the line did something you are unable to. They looked at the ability of each individual that you think is 'making money' for the company, and evaluated whether that person would be able to make more than the cost of the additional support person if a support person was hired, and what the expected return on investment in that person would be before they even opened that position for a manager.
_Every_ person working at a company is expected to contribute to the company's botom line. If they are in a position that doesn't contribute in some way or another, they don't belong.
And if you continue to treat your IT staff as if they don't belong to the company, because you are incompetent enough that you don't understand how vital your IT department is to your company, you are contributing to the sense that your IT staff doesn't belong, and you should expect that your IT staff will recognize that, and treat you like the enemy of your company that you are treating them as. And if you are in upper management and are treating your IT staff this way, you should expect no loyalty from anyone in your IT staff.
And in your example, the user does know more than 'Word is just not working right.' they know that when they attempt to print a PDF, Word does something unexpected. (put up a dialog with strange content, closes, makes the screen start doing odd things...) In most cases the fact that the user can only say 'Word is not working right' means that an IT tech has to come to the desk the user is at, or possibly gain remote access through an internally approved remote desktop support platform, and find out exactly what the user is doing that causes the problem to happen.
As for Facebook or other social sites, it's very rare that your IT department has specified those decisions. Almost everyone in your IT department knows full well that social websites, news sites, and e-mail sites on the web are almost invariable safer for your computer than the internal e-mail system and very likely the intranet environment that you have in house. In almost every case, the reason that your corporate policies marke these resources off limits has to do with the perception of the people making policy with respect to what they expect that employees will be doing on these sites, and how that will affect performance. In some companies there may be liability issues as well related to the possibility that internal information may end up becoming generally available on the internet, which can open the company to liability for privacy issues through insider trading issues and worse.
