Anti-freedom bias by employers

I’m doing some research on employers that enforce an anti-freedom bias on their employees.  I was inspired by the recent American Rifleman article and some other events.  I’m just getting started but I ran across this “Hiring Guide” and I would rather not pay the $20.00 for it.  Does anyone else have access to it?  If so can you tell we if it says anything about gun ownership or free speech advocates?  A sample of the description of the guide:

This guide presents valuable tools and approaches:

  • Critical Behavior Traits
  • Checklist for Evaluating Resumes
  • Important Questions to Include in the Employment Application
  • Interviewing Techniques
  • Reference and Background Checking
  • Employment Verification and Release Form

If not it, how about any similar hiring guides–even if they are specific to a particular company.
