Professional-managerial class. Basically people with white collar jobs who have more sway than the working class due to professional moats (university degrees, accreditations) and more influence on society due to controlling to some degree how capital is deployed.
The point here is that getting blacklisted is probably a much scarier prospect for the manager. PMC jobs typically have more stringent reference checks and employment history requirements. Meanwhile a low-wage grocery store clerk is going to have no trouble finding another shitty job. Typical minimum wage jobs just want someone who will show up and doesn't have a criminal record.
