Danish union joins strike action against Tesla by Swedish workers

Pressure grows on US electric car company to grant collective bargaining rights to employees

Denmark's largest trade union has joined strike action by Swedish Tesla workers, piling pressure on the US electric car company to agree to collective bargaining rights for its employees.

Members of the Swedish trade union IF Metall have been on strike for six weeks - attracting support across industries, including from postal workers, painters, electricians and dock workers who have all launched secondary action.
