My work just posted a list of employees who are near or at overtime on the punch clock.

As the title says. The list shows first and last name of the employee and their hours worked last week. I work for a large company and this list is in full view of customers as well. People near or at overtime are highlighted in yellow. I’m not sure what the motivation is here? Shame those at overtime? Some people who are highlighted aren’t even near over time, 30-32 hours worked for example.
