The very first rule of PI/mentorship is get your trainees first author publications.
This is the thing of biggest lasting career impact that you can determine almost with absolute control.
Yes, things happen but if you are not getting the vast majority of your trainees first author pubs you are screwing up as a mentor.
So. 2017 is about to start. Do you have a publication plan for all of your postdocs and later-stage graduate students?
Obviously I am in favor of active management of trainees' publishing plans. I assume some favor a more hands-off approach?
"Let the postdoc figure it out" has an appeal. Makes them earn those pubs and sets them up for later hard times.
The problem is, if they fail to get a publication, or enough, their career takes a bad hit. So ability to grunt it out isn't ever used.
