Question

What prevents unions from bargaining for the highest possible wages?

Answer 1

Unions no longer bargain for the highest possible wages or benefits, they are bargaining for their lives today.  Wages & benefits are being reduced in most of today's industrialized nations. Corporations have the upper hand due to globalization & the ability to relocate, outsource or import cheaper labor.  Beginning about 1980 the word "union" became a pseudonym for "reduced production & increased expenses" therefore Union busting has become the battle cry for most corporations. Some Corporations have resorted to declaring bankruptcy or surrendering to a takeover bid to rid themselves of unions or raid the retirement fund.

Answer 2

Corporate special interests

Answer 3

Unions do bargain for the highest possible wages. Employers bargain for the lowest possible wages. Usually they meet somewhere in the middle.

Answer 4

Full Employment
