His accusers are Republicans. This apparently relates to the payout of unused sick leave hours from his prior office. It doesn't seem very likely that he ordered the payroll/personnel department to treat him differently than other separating employees. It's possible, of course, that they historically, and consistently, handled these payments in a way that appears to vary from their written policies, but that's not down to him.
My leave pay was calculated the same way as all other management employees no more, no less, Schnirman wrote in an op-ed in the Herald in May. I reported my time off to the payroll staff as I took it, like all employees, and I played no role in calculating my own leave pay. It was based on a legal interpretation made years prior and applied evenly for many years. While my understanding is that all payments were calculated properly, if a review shows the city made any error in my payment, I would immediately return any overage.
