The worst morale boosting gesture I've experienced
If it had been actually senior managers emerging from their offices to walk the open-plan spaces - that would have been pretty nice. Sure, it might have been slightly hollow, but having the CxO stop by for a little chat and word of encouragement is a hell of a lot less synthetic than paying people to pretend that you're doing well.
I don't know how much it cost (thanks shareholders!) - but I'd much rather have the cash. Or a book token. Or a free lunch. Or anything material. It's hard to fake a sandwich.
