"If a company wants to avoid unionization, what is its best strategy? "

I think companies have figured this out hence, union membership is declining. Union growth comes if workers feel squashed. The government has provided workers a lot of what the unions once did. Companies have come a long way since the company owned mining towns and the advent of the Molly Maguires to protect the miner's families.

The Reagan Democrats are not wanted by today's Wall Street Republicans.Right now the old union types like police, firemen and trapped miners are just photo-ops. I imagine the union California firefighters better get ready for invites.
