On Monday, Jewel Food Stores in Chicago, part of the Albertson’s chain reinstated the Mask Mandate for all employees and put up signs “strongly encouraging” customers to wear masks while shopping.
Many sheep obeyed.
I live in downstate Illinois and had that happen a few weeks ago. Our county jumped into the high transmission level and several stores I shop at had their employees wearing masks. As soon as the transmission level fell to medium masks were again optional for employees. I think it is just the corporations following CDC guidelines..
