Histadrut leader Ofer Eini has compared Israel’s growing use of contract labour to a slave market as the union federation announced a general labour dispute over the issue.  The issue of precarious work and outsourcing is being faced by unions all over the world, but few are taking it head-on in the way the Histadrut is.  The unions have the support of the broad social movement that set up tent cities and had rallies of tens of thousands across Israel in the last few months.
