Where I use to work, and the airport 'owned' ATC, the ATC Watch Manager was effectively the Airport Ops Manager so we took the decision. Then as Manager ATC I owned the whole problem!
The troops had a standing instruction to phone me when it was snowing. I struggled home once in a blizzard only to walk through the door to be handed the phone to be told "It's snowing" . . .
Then we joined NATS and I could put my feet on the desk until someone told me the runway was open . . . .
