CMP (Energy East) has again discovered a raft of apparent errors in their payroll system. Although the problems are apparently company wide for Energy East and include both union and non-union workers, 131 IBEW 1837 members have received letters either asking for refund of alleged overpayments or with checks for alleged underpayments. Many but not all of the errors are related to 401(k) withholdings. Others are apparently miscalculated callouts and other miscellaneous errors.
