Security guards are the latest group to confirm they will take part in what is set to be the biggest day of industrial action in the UK in decades.
Members of the IWGB union working for contractors at London university UCL will stage a walkout on February 1 as part of a campaign for a pay rise to £15 an hour. Meanwhile, teachers, train drivers, civil servants, and university lecturers will go on strike on the same day in growing disputes over pay, jobs, and working conditions.
The TUC will also organise a nationwide protest on February 1 against the government's controversial proposed law on making unions agree to provide minimum levels of service during strike action. Unions have argued that the legislation will allow workers to be sacked even though they legally voted to strike.
