P 713.212.2647 | F 713.963.0859


Merritt Chastain provides proactive traditional labor and employment counseling and handles related administrative proceedings and litigation, helping his clients first avoid workplace disputes and potentially costly mistakes, then successfully resolve matters in and out of court when necessary to minimize liability and financial exposure.

Leaning on years of experience, Merritt regularly handles a broad range of labor and employment issues from preparation to litigation to appeals, while also representing management in union disputes. Merritt has considerable experience in providing legal counsel and representation related to union organization and decertification campaigns, collective bargaining, labor arbitrations, strikes and picketing, and unfair labor practice proceedings before the National Labor Relations Board.

His counseling work for employers of all sizes includes a thorough understanding of labor relations, federal and state labor laws, discrimination laws, OSHA guidelines and recommendations, federal and state wage and hour laws, and other laws pertaining to the employment relationship. He further works closely with clients to draft comprehensive employee handbooks and policies that guide all decisions related to the employer-employee and labor-management relationship, employment agreements ranging from simple to complex, arbitration agreements, alternative dispute resolution programs, and executive compensation packages that assist in attracting and retaining top talent.

Merritt’s representations include employment discrimination, OSHA citation, Employment Retirement Income Security Act (ERISA), and related litigation. He has also successfully resolved and litigated matters involving misappropriation of trade secrets, violation of covenants not to compete, breach of employment agreements, and the pursuit and attainment of injunctive relief.

Based on a prior clerkship with the Texas Supreme Court, he also has cultivated a vibrant general appellate practice and has argued and won cases before most of the courts of appeals in Texas, including several before the Texas Supreme Court, and many courts of appeals in other states.
