BOSTON (AP) — The Dartmouth men’s basketball team is dropping its attempt to form a union. The team is ending a push to become the first college sports team to unionize in order to avoid a potentially damaging precedent from a National Labor Relations Board that soon will be controlled by Republicans. The Service Employees International Union Local 560 filed a request to withdraw the NLRB petition on Tuesday rather than take its chances with an unfriendly labor board.
