From the article

“ That’s about $45 each on average, the lawsuit notes. The actual individual payments will be calculated based on the employee’s tenure with the company, but each one will receive at least a fixed payment of $20, with an additional $22 to $59 tacked on for many.”

The average dollar amount per employee and the amount each employee will actual be paid are not the same.

I believe it’s been ongoing for months (sense March)
