Sen. Bernie Sanders unveiled a new labor plan Wednesday that includes a proposal to let federal employees go on strike.

“Under current law, federal employees are not guaranteed the same labor rights as workers in the private sector. While they have the ability to unionize, they are prohibited from going on strike,” a plan summary said. “Under this plan, federal workers would have the right to strike.”

The campaign of the 2020 Democratic presidential hopeful noted that the recent partial shutdown led to many federal employees being required to report for work despite not being paid.

“In December, Trump shut down the federal government for 35 days — the longest in history — depriving over 800,000 workers of their paychecks. Adding insult to injury, hundreds of thousands of TSA agents, air traffic controllers, IRS employees, members of the Coast Guard, and other federal government employees were forced to work without pay and without recourse,” the campaign said.

It was not immediately clear how much the plan to allow federal employees to strike would apply to the legislative branch or what kind of national security exemptions might exist.
