In his statement explaining his decision to switch from the Republican to the Democratic Party, Sen. Arlen Specter assured his listeners that "my position on Employees Free Choice (card check) will not change." In later statements, Specter was explicit in opposing both major provisions of the bill -- the effective abolition of the secret ballot in unionization elections and mandatory federal arbitration -- and said he would not vote for cloture.

Whether or not Specter maintains his current stand, he has spotlighted an interesting issue. The labor unions' drive for the full card check bill seems to have foundered. Specter enters a Democratic caucus where a half-dozen or more senators have made it clear, publicly or privately, that they will not vote for card check.

His statement gives cover to a Democratic leadership that wants to propitiate its labor union funders but does not want to put so many of its members on the spot. A vote to effectively abolish the secret ballot is not easy to defend come election time.

But the unions may have a fallback position: Forget about the secret ballot, and try to pass a bill with mandatory federal arbitration. This might be easier to defend. Every American knows what the secret ballot is; few Americans know what mandatory arbitration means.

Mandatory arbitration would be a major, massive change in American labor law. Currently, unions are free to strike, but employers are free to resist their demands as long as they want. The card check bill would require, after only 120 days of bargaining, a federal arbitrator to step in and impose a settlement. A centralized bureaucrat, not responsible to shareholders (or to union leaders), would determine wages, fringe benefits and working conditions. There would evidently be no appeal.

No one knows exactly what this would mean in practice. But the negative consequences are easy to imagine. Arbitrators might very well impose terms and conditions similar to those in existing union-negotiated contracts. Those might include not only wages that would reduce a business' profits, but also generous fringe benefits and thousands of pages of detailed work rules. Continued...
