I have never seen a single instance of an academic sector job posting that explicitly required project management skills, never mind certification.
This is madness.
I am thinking of getting a PMP cert anyway.
Update: As a Canadian citizen I appear to be eligible for some of these postings at the UKMO; I have (as the Brits would say) half a mind to apply. Farewell tacos, gorditas, enchiladas, beer with fresh lime, margaritas... ?
