"Across the United States, we are seeing workers walk off the job in wildcat strikes in response to the employers’ failure either to shut down the workplace or to make it safe. The strikes are too few to call them a strike wave, but we should be aware that on their own initiative workers are taking what practically is the most powerful action they can: withdrawing their labour. The strikes are taking place in both the private and , in both unionised and non-union s large and small."
