C&C is being encouraged to engage with staff at M&J Gleeson in Borrisoleigh as soon as possible to outline their plans for the company.
This follows the decision by the Competition Authority to clear the way for C&C to proceed with its acquisition of Ireland's leading drinks distributor.
C&C, which owns the Bulmers and Magners cider brands, will pay €12.4 million with €4.4 million deferred for a year.
Gleeson's debts of €45.6 million will also be taken up by C&C.
Deputy Michael Lowry says staff have been kept in the dark up to now on what C&C's plans are.
