No, they use it the first day, and then progressively less. Since this has happened a few times with different tools management has abandoned hope.
"What is the status of issue X?"
"What is the IssueID?"
"I didn't create one"
"Create an new entry in the tracker and we can all track progress of issue X"
Repeat as many times as necessary.
edit: I also try to create a trigger or other automatic action in the tool. For example, our issue tracker updates the release notes when items are modified or marked as completed. If you can get people to use the triggered tool it will create an incentive.
