In Nagy v. Employees' Review Board, 249 Conn. 693, 735 A.2d 297 (1999) the Court held that the hourly calculation of sick and vacation leave authorized by General Statutes 5-247 and 5-250 "may not operate to reduce the total number of days of sick and vacation leave that an employee has earned. Consequently, 5-247 and 5-250 entitle the employees to the number of days of sick and vacation leave previously earned, despite an increase in the number of hours in their standard working day. Therefore, pursuant to 5-247 and 5-250, an employee who earns one day of sick or vacation leave is entitled to utilize one day of sick or vacation leave regardless of any lengthening of the standard workday."
