This this this. Split PTO is an accommodation for disabled and chronically ill folks that allows them to have actual vacation and also take care of themselves. Unified PTO penalizes people who need time off work to care for themselves regularly. If you're disabled/chronically ill you maybe be able to use intermittent FMLA (in the US) to take more sick time but this is unpaid and can be a big hassle, esp if your employer/doctors are not supportive/cooperative (which can be a result of incompetence/ignorance as easily as malice)
