Employment law is an extremely specialized field of law. Those seeking advice and/or representation with respect to an employment law issue should take care to consult someone who is knowledgeable and experienced. I have been actively practicing employment law for almost 25 years and am competent to handle any employment-related case you may have.

As a skilled San Antonio Labor and Employment Attorney, I am experienced in resolving both employees' and employers' labor and employment law issues, in the following areas:

  • Employment Discrimination (Race, National Origin, Sex, Age, Disability, Religion)
  • FMLA
  • Non-Compete Agreements
  • Severance Agreements
  • Arbitration
  • Unfair Labor Practices
  • Breach of Duty of Fair Representation
  • Employee Rights
  • Wrongful Termination
  • Sexual Harassment
  • Overtime Compensation
  • Defamation 
  • Trade Secret Agreements 
  • Whistleblower Claims
  • Administrative Law

I take pride in representing all kinds of employees in a variety of challenging situations. For example, I negotiate severance agreements for laid off or terminated employees. I represent terminated employees in regard to claims for unemployment benefits, and I represent employees who have been discharged or otherwise discriminated against because they sought workers' compensation benefits. I also advise and represent employees in regard to non-compete agreements.

I represent employees who have been victimized by unlawful employment discrimination in proceedings before the U.S. Equal Employment Opportunity Commission (the EEOC) and in federal and state courts. I represent federal, state, county and municipal employees in appeals to the U.S. Merit Systems Protection Board and in similar state, county and municipal civil service proceedings.

I represent state and local government whistleblowers who have been retaliated against by their employers. I also represent public school administrators, teachers and support staff in grievances, complaints and appeals to the Superintendent and/or School Board, and in federal and state courts.

I also advise, counsel and represent employers in many of the same types of situations. For example, I represent employers in defending claims for unemployment benefits, Texas Payday Law claims, and claims of discrimination before both the EEOC and the Texas Commission on Human Rights, and in federal and state courts. In addition, I advise and counsel employers in regard to hiring practices, personnel policies and procedures, wage and hour issues, promotion decisions, disciplinary actions, and termination decisions.
