Ann Scott Tyson reports that the workers were chanting "Hey hey, yo yo -- you and your buses got to go!" prior to the start of board committee meetings being held this morning.

Jackie Jeter, president of Amalgamated Transit Union Local 689, says the protest is over Metro management's unwillingness to follow binding arbitration.

Later the workers filed into the meeting room and stood silently as the proceedings began.
