Britain is working on several options to tackle the shortage of truck drivers, including luring former employees back to the market amid warnings from the food industry that supply chains could break down in the run-up to Christmas. Tesco ($TSCDY@UK), Britain's biggest supermarket group, told government officials last week that the shortage of truck drivers could lead to panic-buying for the holidays if the action were not taken. The trucking industry says it needs another 90,000 drivers to meet demand after Brexit made it harder for European workers to drive in Britain. The pandemic prevented new workers from qualifying. Supermarkets, farmers, and other operators have called on the government to allow workers from abroad to return to British roads. The National Farmers' Union has also written to the prime minister asking him to introduce a new visa system to help tackle the labor shortages across the supply chain.
