Interview coming up for academic post. Been a bit of a lull in my research output over the last year cos I've been on maternity leave. If this comes up in interview (the lack of outputs over last year) should I say I've been on mat leave? I don't want the fact that I have small children to count against me (even if it's unconscious bias), but also don't want them to think I've been doing nothing for a year for not good reason...
