The end of 2022 was marked by mass industrial unrest as employees across the transport network, NHS, Royal Mail, schools and the civil service took strike action. The start of 2023 will bring further stoppages by rail workers, bus drivers, teachers in Scotland, nurses, ambulance workers and civil servants. Unions are warning of an escalation in their activity. Rishi Sunak’s government is braced for strike ballots to close in January for teachers in England and Wales and firefighters, while junior doctors will also be balloted early in the new year.
