Do single faculty members (regardless of gender) experience more scrutiny come promotion and tenure. Does their marital status lead others to think they should have more articles than a faculty member with a spouse or children (or both).
I've known of a couple cases where a single person was asked "why don't you have more of a record. You have more free time." And I've heard others say "[they] don't have a lot of recent publications, but they have three kids"
If you're a single faculty member do your colleagues think that you automatically have more time than them (i.e. because they really have no idea what else you may be involved in), and that therefore you should be the publication star of the department (i.e. using all your free time to publish)?
