MBTA employees average 57 days absent from work per year, according to findings by a panel appointed to assess the T’s management, The Boston Globe reported.

The panel blamed what it called “excessive absenteeism’’ on “weak MBTA management,’’ and attributed thousands of canceled trips on unplanned absences, according to the Globe.
