One of my former students left his PhD program while ABD and now has a very successful career in labor organizing. He was successful in helping to organize a union for grad students while in his program, which made him a very desirable hire.
Hmmm. I'm pretty sure you're not at the same university as I am or in the same field, but I can register a legitimate +1 to this post, except that it's his wife who was my student; he was in a different subfield within my department.
