The government also said interim payout has already been announced for employees.
State government transport corporation employees affiliated to 11 trade unions including DMK's labour wing Labour Progressive Front are on strike since Sunday.
However, drivers and conductors affiliated to ruling AIADMK's Anna Thozhir Snagam worked.
About 200 employees were detained across the state in connection with strike-related incidents including alleged stone pelting on buses, police said.
Trade bodies urged government to start talks to conclude a wage settlement agreement but the latter wondered how it could go in for talks when a case was pending in the Supreme Court.
Chief Minister O Panneerselvam said, "some LPF employees misled by the DMK have not reported for work but have also indulged in violence."
Legal action has been initiated against them, he said. A case is pending in the Supreme Court on the question of a trade union with which talks could be held for concluding a wage settlement agreement, he said in a statement.
After the apex court judgment, an appropriate agreement will be inked, he recalled his previous assurance.     

"Karunanidhi should ponder if it is correct to instigate employees to go in for strike," he said, adding, the DMK's LPF was in a minority.
"As on November 30, 2014, LPF has only 13.96 per cent (18,000) of employees on its rolls. Anna Thozhir Sanga Peravai (affiliated to ruling AIADMK) has 70.90 percent of members (91,440) with it," he pointed out.
He said about 70 percent of buses were operated on Monday and hoped that cent percent buses will run on Tuesday.
