Best I heard off was Exxon UK
During a holiday or long weekend, management would call in contractors who would move furniture, seal off the openings to offices with plasterboard and cover up the gaps perfectly. Offices or whole sections would disappear or teleport to new location.
Come Monday, frantic people would return to the reception inquiring about their office, some of these would be given directions an a reprogrammed access badge, others would instead be given a bin-liner with the contents of their desktop.
Totally in the spirit of Management Guru: B. F. Skinner.
