"While some companies have given their employees time off on Friday, from a purely legal perspective employees must perform their work unless they take proper leave. However, from a tactical or ideological view, it makes possible sense for employers to extend the lunch break or even to release employees from 12pm for the rest of the day to allow them to participate," she said.
Climate change activists backed by the Swedish activist Greta Thunberg have called for a 'global climate strike' for a week starting on 20 September. People around the world will be asked to walk out of their place of work to "show our politicians that business as usual is no longer an option".
The aim of the strike is to replicate in the workplace the mass walkouts of school students that have attracted significant publicity and political engagement around the world.
In Germany, strikes can only be called by trade unions, and only in relation to issues that can be regulated in collective agreements. Although Verdi, the German trade union, has encouraged its members to participate in the protests, they have not been asked to 'walk off' work but only to join in once they have finished work for the day, according to the Associated Press.
