We are a employer; we have a union trying to organize us for Ironworkers. What are laws that protect the company? We are being harassed,losing $

This matter is too complex and too time-sensitive to waste time looking around on a website looking for free or ad hoc advice.  National labor relations laws are very worker/union friendly and responsive conduct which seems reasonable to the employer could generate an unfair labor practice complaint to be used as a lever by the union to gain an advantage in any representation election.  Also, recent amendements to the NLRA election rules make union election petitions a very quick process. Unless you want a union representing all of your employees, my best advice to you is to IMMEDIATELY find and hire a qualified labor attorney who has experience in fighting unions.  These folks are not easy to find in Texas because unions are not predominant in the workforce here.  Ask a lot of questions.  Employment lawyers are not the same as labor lawyers, even though they may hold a board certification in "labor and employment law."  Try www.lawyers.com or its sister site www.martindale.com. Look for indicators that the attorneys who show up in the search results have labor/management, union election, NLRA or NLRB experience.
