Snow (noun) White powder used by British workers to avoid actually working.
I donned my walking boots, daft hat and utterly unflattering bad weather jacket and braved the great outdoors. My bus took exactly three minutes longer than normal to get to work and yet 40% of our staff failed to arrive. Even if half or two-thirds of those were parents dealing with school closure there is still a significant number who opened the curtains, grinned and swiftly jumped back into bed for a duvet day. Goddamnit, I wish I'd thought of doing that.
