USA-based small business owner here in a right to work state. I've got a salaried employee who has depleted their PTO days but is still calling out sick. I'm not sure exactly what to do. They earn a certain number of PTO hours each paycheck but this individual has depleted those hours entirely.
Is it legal to reduce their salary by the number of hours they're in the red or is a negative PTO balance better? They may be on their way out anyway so I'm not too concerned about retention but want to protect the business / not pay for someone who isn't working.
