Four months before it won a $5.3 million jury verdict against a union that allegedly disparaged it, Professional Janitorial Service of Houston hired a new team of litigators, led by John Zavitsanos of Ahmad, Zavitsanos, Anaipakos, Alavi & Mensing in Houston, to try the case.

The company added the Ahmad Zavitsanos team even though Professional Janitorial Service had relied upon only the well-known national employment firm Littler Mendelson for the previous 10 years of its lengthy legal fight with the union.
