Feb 27 (Reuters) - Attorneys at U.S. and British companies predict discrimination and wage-and-hour claims will continue to dominate the employment law landscape in 2013, according to a report on litigation trends.

Thirty-five percent of 392 in-house attorneys surveyed expect the greatest increase in their workload will involve discrimination disputes in 2013. Another 29 percent said they expect the greatest increase will be in wage-and-hour disputes, according to the survey by law firm Fulbright & Jaworski.

"Discrimination and wage and hour cases are the dominant concerns among companies of all sizes," the report said. Retaliation is next on the list among midsize and larger companies, it said.

The greatest increase in discrimination cases is foreseen by in-house counsel in the real estate, retail and wholesale and financial services sectors, the report said.

Increases in wage-and-hour cases are expected by in-house counsel in the retail and wholesale, manufacturing, energy, technology and communications, and engineering and construction sectors, it said.

Over the past 12 months, the area with the greatest increases in both multi-plaintiff and individual lawsuits was wage-and-hour disputes, which were cited by 43 percent of respondents, followed by discrimination, cited by 37 percent.

Among discrimination disputes, race was listed by 14 percent of respondents, sex by 9 percent, age by 7 percent and disability by 7 percent. Sex discrimination replaced disability discrimination as the second-most-cited area for discrimination disputes.
