There has been a surge in the number of workplaces in the United States voting to join a labour union. Amid this wave of unionisation, companies are pushing back hard. We find out what is happening in the US and how businesses and politicians are reacting.

We hear from a worker at outdoor clothing co-operative REI where staff have voted to unionise, plus Michelle Miller, who runs Co-worker, an organisation that supports employees who want union representation. Michael Strain, an economist at the centre-right policy organisation, the American Enterprise Institute, explains that workers are actually doing quite well at the moment as unemployment is low. And have you heard of union-busting? Rebecca Givan is an associate professor of Labor Studies and Employment Relations at Rutgers University in New Jersey - she explains what is happening.
