The head of Israel‘s national workers union announced a strike to protest the Netanyahu government’s inability to secure a hostage deal.

Histadrut Labor Federation chief Arnon Bar-David announced on Sunday that the strike would only last a single day, on Monday, and that any further strike would be decided later. The Histadrut is one of the most powerful organizations in the country, boasting over 800,000 members in a country of 9.6 million. The strike risks crippling the country.
