Many learned followers have expressed their views. I appreciate their effort and would like to add mine as well.
Union's Identity and Legal Standing
As per the TU Act, the Union has its own identity and is a company for all practical purposes. It has its own registered office (either owned or rented), a team of office bearers who run the affairs of the TU, a code of conduct, books of accounts, etc., just like any other company registered under the Companies Act.
From the above, I feel that I have made myself clear that the Union cannot—I repeat, cannot—demand as a matter of right to be allowed to open its office on the factory premises. However, since they are one of the important agents in the process of production, productivity, and profitability of any organization, it is in the interest of the management to provide the recognized Trade Union space for running its office at a suitable place, but never within the premises of the factory or production place. The management must charge a token rent (however small it might be, even like Re.1/-), to establish their ownership over the premises provided to the TU.
Best wishes.
