Labor's Secretary-General Eran Hermoni met with Labor leader Avi Gabbay on Thursday morning and told him he should have already quit his job immediately when exit polls revealed that Labor won only six seats.
"After the results were such a disaster, he should have taken responsibility and resigned," Hermoni said.
He said Gabbay's departure was the needed first step in a healing process for the party.
Hermoni was eleventh on the Labor list.
MK Eitan Cabel, who was 15th on the list, said in radio interviews on Thursday that if Gabbay followed the rules of the business world, where he came from, he would have already been handed his belongings and ordered a taxi at his own expense.
