Or, even easier, just pay your workers well, give them decent benefits, and do union busting to prevent them from forming in your company. Why outsource treating workers well to a bureaucratic middleman when you can just treat workers well yourself? (keep in mind this is for small businesses, not mega-corporations)

>Wouldn't that corrupt union leadership over time?
No, you would pay employees using profits in part, and implicate them into the decision-making process. That way the incentives of union-leadership, workers, and stakeholders align. You can also push for union structures that minimize the power of union leadership and instead give it to the rank and file. Basically, making your company a bit more into a worker-coop fixes the issue.
