Congress has issued a three-line whip to its members in Lok Sabha asking them to be present during proceedings on December 7 and 8.
Parliament sources said this has been done not for any particular issue but keeping in view the possibility of some "important business".
The development has come at a time when Parliament has remained paralysed for the last nine days on several issues including over FDI in retail.
The opposition has been demanding a rollback of the FDI decision and has been pressing for an adjournment motion on the issue so a censure the Government.
Logjam has prevailed in Parliament despite government's efforts to placate its allies - DMK and Trinamool Congress -whose members vociferously protesting the FDI move.
The two Houses will now meet on Wednesday. The current session is slated to conclude on December 22.
