Using the table below, you can sort and filter the union halls.
Click on the headers to sort the table. Click the “Town” heading to sort by web address, the “Call Letters” heading to sort by the call letters, the “Full Name” heading to sort by the full name, the “Local Name” heading to search by local name, the “Notes” heading to sort by notes, the “Web Site” heading to sort by web site link, and the “More Info” heading to sort by the more info link. The first time you click the sorting direction is ascending (A through Z). Click again, and the sorting direction is descending (Z through A).
To filter the results, type in the search box. As you type, only the relevant results will remain in the table. To see all results again, simply clear the search box.
To change which columns are visible, click the “Column visibility” button, and then click a button from the list (which drops down) to alternately remove or replace the corresponding column. If you see a green circle with a plus symbol (+) inside, you can click on that to see even more data.
To visit any union site, simply click on the address in the “Web Site” column, and the corresponding page will open. To find out more about any union (such as membership size, financial information, and so on), simply click on the address in the “More Info” column, and the corresponding information page will open.
We strive to keep this list as updated and accurate as possible, so if you can provide more complete and updated information than you find below, please contact us at [email protected] with the subject heading “Union Hall information”, and we’ll be glad to add that information.
