THOUSANDS of people will rally across the United States tomorrow in defence of their trade unions, as the Supreme Court prepares to start hearings on a case that could deal a severe blow to unions’ funding.

The Working People’s Day of Action takes place in the run-up to Janus v AFSCME Council 31 reaching the court on Monday.

The case, brought by Illinois state worker Mark Janus but funded by groups linked to wealthy corporations and billionaires, threatens to make all state and local government workplace a “right to work” site.
