Israel’s largest trade union group launched a strike across a broad swath of sectors Monday, joining a surging protest movement against Prime Minister Benjamin Netanyahu’s plan to overhaul the judiciary — a plan that is facing unprecedented opposition.

The strike by the Histadrut umbrella group, which represents nearly 8,00,000 workers in health, transit and banking, among many other fields, could paralyze large parts of Israel’s economy, which is already on shaky ground, ratcheting up the pressure on Netanyahu to suspend the overhaul.
