Martin,

1) The NLRA and RLA are established law with long standing precedence.

2) Anyone who submits a résumé/application to work at a closed union shop is doing so (assumedly) under their own free will and with the intention to obtain gainful employment. By doing so, you're agreeing that your employment will be governed by a Collective Bargaining Agreement between the Employees (which you want to be a part of) and Management.

The bottom line here is, IF you don't agree with the idea of unions then don't apply to a union property. There are plenty of non-union properties out there. Knock yourself out.

If you're already employed by a union property, see point two.
