How can you tell if your employees are genuinely sick? Use a lie detector? Or rely on the “Fit Notes” from the GP (which, by the way, an enterprising part of the economy has started falsifying and selling online!) Part of this uncertainty will however soon be a thing of the past.
Next year, the NHS is introducing e-Med for GPs where each Fit Note will be completed by computer and with a unique barcode on it. That makes it easy for you to check that it is genuine and really difficult for the budding entrepreneurs to falsify.
