I maintain a web page that tracks tasks for my team. There is a column currently called "not started" that we use for tasks we haven't started yet. We would also like to use that column for tasks we started, but didn't complete, that no one is actively working on for the time being. However, people are reluctant to move it back to that column because the label implies no work has ever been done on that task. A fourth column isn't really an option due to space constraints.
What's a phrase that succinctly captures both meanings?
