A London bus driver has criticized Mayor Sadiq Khan after Khan said Transport for London (TfL) workers would not be penalized for refusing to drive buses that are not properly equipped for hot weather. The dispute centers on TfL buses during the four heatwaves of 2026, when many vehicles reportedly lacked working air conditioning. According to the reporting, bus drivers were among the worst affected workers in the city during those periods, with complaints focused on passenger comfort and working conditions when cooling systems were not functioning. The driver’s comments challenge the mayor’s assurance and highlight concerns about how such refusals would be treated in practice. The coverage frames the issue as part of a broader accountability debate over TfL vehicle maintenance and staff protections during extreme temperatures. The matter is presented as a disagreement between a frontline worker and the mayor’s stated approach to workplace penalties related to operating conditions during heatwaves.
