It's both. For example, when we take an extension on a file, there's a standard phrase in the letter that goes to the client: that it's disruptive to the operations of the department.
For example, we have a task force in Afghanistan. I consider I work long hours, but I don't work anywhere near as long, nor am I under the same stresses, as our Afghan task force is.
If you look at the lists of requests the department gets on topics of international issues, they tend to be the issues that are on the front pages of the newspapers. So it's Darfur, so it's Afghanistan, so it's Haiti. There is a direct correlation. It's the same subject-matter experts who are being tapped over and over again.
So as Ms. Sabourin pointed out, there are capacity issues, and there's a very significant increase in volume and complexity of the files.
