In Australia collective bargaining workplaces unions negotiate the pay structure and benefits for all workers, members or not. This leads to some arguments that non union members benefit from the unions without paying the fees, and indeed, in my mostly white-collar government workplace only about 10% of workers are union members. Unions mostly exist for unskilled workers (the most replacable) or specialised workers whose skills don't easily transfer elsewhere.
