Officials with Keolis confirm that two more employees were fired on Monday for rigging their time cards.
The terminations come after six employees in the company's mechanical department were fired last week for the same offense.
Keolis spokesperson Leslie Aun says another employee will have a hearing later this month to determine their employment status.
It's still unclear if charges would be filed.
Keolis is the French company that manages the MBTA's commuter rail system in the Greater Boston area.
