Hardys & Hansons shareholders have approved Greene King's £271million takeover bid.
Almost 96% of Ordinary shareholders voted in favour of the move.
Greene King now looks set to gain control by September 5.
The takeover has raised concerns about the future of brewing at Hardys' Nottinghamshire brewery.
But Hardys and Hansons managing director Jonathan Webster said: "Of our 2,000 employees, 1,800 are at the pub end and being part of a larger pub group will create opportunities for them.
"I think the question marks are at the brewing and the head office end - Greene King haven't declared what they intend to do.
"Generally their approach is to run a business for a period of time before making decisions."
Campaign group Camra fears Greene King will move beer production from Kimberley to its own Suffolk brewery and yesterday we reported the fears of a Kimberley councillor.
