In the United Kingdom, strikes are becoming rarer, but social mobilization remains topical. For the past year, trains, schools and hospitals have been striking to demand better pay and working conditions.

This Tuesday, May 30, it is a major player in the charitable sector that begins a month-long mobilization: the NGO St Mungo's which supports homeless people. The Unite union has set up a strike fund to support employees during these four weeks of mobilization. "We want to be at work and help Londoners most at risk, and instead we are there holding signs," says one striking worker.
