DFCC Bank owns a 29.8 percent stake in Commercial Bank with special permission from Central Bank.
Companies connected to the Stassens group of companies hold substantial stakes in both DFCC Bank and Commercial Bank.
But employee unions have opposed moves by Stassen group companies to gain operational control of Commercial Bank.
CBEU President M R Shah said the union, which met the president this week, had also asked pensions paid to state bank employees to be restored.
In 1996, the government decided not to pay pensions to new employees as part of the restructuring exercise of state banks, when public money was used for the second time to bail them out.
A part of the money, even at the time, went to plug holes in the pension funds.
