As The Sun's Erica Green reported Tuesday, Baltimore allows employees to cash out much more leave time, sick time and vacation time when they leave the system than other districts do. Year-round employees in the Baltimore Teachers Union can cash out up 72 unused vacation days, according to the current contract, while principals can be compensated for up to 250 unused sick days when they retire. Other employees can get even more. By contrast, Baltimore County caps pay for unused leave time at 40 or 45 days, while Howard County caps it at 40. And neither of those districts allows retirees to cash out unused sick leave.
