The day that cost two days

Staff shortages. Someone has to be moved 'for one day, because there's nobody else'. An agency worker gets an assignment described briefly: stones to lay on the roof. On site it turns out the 'stones' are freshly coated concrete roof tiles with a bituminous-acrylic coating. In full sun, on a hot roof, over five hours of feeding them up — solvent fumes go straight into his face. Nobody warned him what he'd be working with, so he had no mask with a carbon filter. He came down from the roof with a headache and dizziness. The next day — absence.

Not in the bitumen. Bitumen on roofs is standard — the whole trade covers roofs this way. The material wasn't the mistake. The mistake was information that didn't pass through the assignment chain: • Someone knew what the roof was coated with. • Someone else decided who to send there. • A third person wrote up the assignment. At none of these handoffs was one thing connected: what we're laying with who lays it and what they will need to do it safely and well. Three cost items from one badly described assignment: a paid working day, a lost day of absence, and the dented trust of a worker who next time will ask twice before stepping onto anything. Why this is margin, not just health and safety: because the same mechanism — knowledge is in the company but doesn't reach the point of decision — leaks money everywhere, not only on the roof. A crew sent without the full set of materials → downtime, a second trip. An assignment with no information about conditions → worse quality, rework. A resource 'borrowed' for one day between projects → nobody counted the real cost of that loan. Each on its own looks like a trifle. Summed over a year it's margin that evaporated, and nobody can point to where.
