So a couple of days' notice.
OK, I see.
Thing is, the number of people that SEE such warnings is pretty low.
That board had an announcements forum, which probably helped...and they were small, so there was likely a lot of word of mouth, and they seem to be a pretty alert and switched on group.
But look at what hawk just said "Nobody ever told ME there was to be a switch to a new A2k" The place was awash with notifications and discussion about the move...but lots of even well-intentioned people didn't see them!
I heard a great story at work about just this sort of thing today.
A group of our staff went up to a ward to have their flu shots the other day. (The 'flu trolley moves around.)
They had to fill out forms + consents, and L didn't have a pen.
She saw one in an adjoining private closed room, (a patient bed room...but the bed was empty) and ran in to borrow it.
She was filling out the form (and biting the pen) peacefully, and couldn't understand why her colleagues and the flu nurse were agitated and telling her to drop the pen.
Turns out she had simply not noticed that the room she so casually entered was literally festooned with huge red warnings not to enter without a bio-hazard suit (you know those moon suits you see on films about horror microbes) because the patient had a dangerous and highly infectious disease!!!!!
All she saw was a pen.
