I have two mentees - Bob and Sue - both international students who studied in STEM here at my uni. I know both their supervisors well socially, although we do not really collaborate much at all.
Both Sue and Bob are in the same predicament - and I am not sure how I feel about it all.
Bob finished his PhD 1+ year ago. He passed with minor but rather big revisions, and his work is ok - nothing about it is earth-shattering, based on the seminars I saw through the year. In particular, the research is very incremental, uses non gold-standard techniques, and the novelty it brings will hold impact for a very very small set of stakeholders who may not actually care at all.
Bob is desperate to find a job, and is struggling without publications on his CV, even with recommendations and my support. So far, his work has been submitted in three chunks (3 chapters = 3 papers) and all have been rejected from at least two outlets with quite strong reviewer (negative) comments, some expressing concern that such work "quality" is even coming out of the supervisors lab. Now the supervisor wants him to reconsider publishing at all, or clump the 3 chapters in one single or at max two papers for submission to a "minor league / open access" journal. The REF, I believe, is the main factor here, based on this supervisors' stance.
The other one, Sue, is in pretty much the same situation - except that I'd say her work is really really striking. She writes really well, and what she did was really interesting, with complex methodology. However, 3 years post PhD, she has not published anything from her thesis (but has, from her postdoc). Her supervisor has effectively put her thesis papers "on hold", to be combined with the subsequent work of others in his lab [these people are not finished yet]. Basically, Sue's research may (or may not) see the day of light, with limited chance for her to be a first author. Again, I believe the REF is a big factor here - this supervisor likes to go for BIG papers in big vanity journals, with his name last, at the expense of the many juniors whose contribution often are very much diluted in the mega papers (which can take years to come out).
So - my question: what is our duty to our students and the academic community? Do we publish everything?
Can either Bob or Sue really challenge their supervisors to go their way?
I find mentoring on these topic harder and harder - the uni's publication strategy is all for REF just now, and the unspoken word to the staff is that we want only big papers, not smaller research to get out.
It's not really fair to the ECR though - job hunting with no paper is hard.
