Des Moines Register: Tyson Foods is reinstating an attendance policy that punishes workers for missing shifts, even as it reports new COVID-19 outbreaks in its Iowa meatpacking plants. The company is returning to the policy it had put on hold in mid-March, when the coronavirus began spreading rapidly through closely spaced workers on the meatpacking lines at Iowa processing plants. Under the policy, employees are assessed points for missing shifts. Those who accumulate too many can be fired.
