Incentives to Employees Who Take Vaccines

Dollar General is giving 4 free hours of pay if employees get the COVID vaccine, but employers can get sued for discrimination if the incentive is too high and eliminates an employee's meaningful choice. We discuss the following questions:

1. Is 4 hours too much?
2. What does de minimis, under the new proposed regulation, even mean?
3. Wasn't there already a court decision on this very issue? 
4. Who is advising Dollar General? 
5. How does this apply to your small / medium business?
