Can the property sign a unilateral agreement with Unicom instead of the owner?

Industry committees are elected by more than half of the owners, so they can sign property service contracts with the property on behalf of the owners. They don't have to vote on everything except under the circumstances stipulated by the property management regulations. It doesn't matter if the number of owners is small. If there are thousands of households, the workload of voting on everything is unimaginable. Moreover, the contract is the result of negotiations between the two parties, which may take several rounds to finalize, and it is unrealistic to ask the owner to vote every time. However, the industry committee shall publish the draft contract to all owners and fully solicit their opinions. After signing a formal contract with the property company, the formal contract should also be publicized to the owner.
