Dear Critic,

«Do you guys think that the company can require employees to wear PPE?

Yes, because if the company is negligent...»

Yes, just as they can require employees to wear clown's hats.
As they pay for the employee's time, they can require their employees to do whatever they like during that time, at their pleasure - unless their contract states otherwise.

In the particular case of PPE, a reasonable company would require it, not in order to protect employees against their will, but in order to protect its customers, in case an employee is contagious.
