Case History

Kuzinski v. Schering Corp. — Kuzinski was a collective action brought on behalf of pharmaceutical sales representatives ("PSRs").  PSRs claimed that they were improperly classified as exempt outside sales persons because they did not exchange prescription drugs with physicians in return for consideration.  They argued, in other words, that a consumated transaction was required to qualify an employee as an outside sales person. 

Ultimately, the U.S. Supreme Court ruled in favor of the exemption.  We represented Schering for over five years and successfully avoided notice being issued to the putative class.
Lopez v. Wal-Mart Stores Inc. — Lopez was the largest known potential wage and hour class action brought in Texas, involving more than 350,000 employees.  Because Texas does not have its own overtime laws (comparable to the FLSA), plaintiffs brought their claims under a breach of contract theory.  We were able to defeat class certification on appeal.
Ryerson Inc. v George Thompson — We represented Ryerson in enforcing its non-compete agreement with the former owner of a company Ryerson had acquired.  The Company demanded, and Thompson's new employer ultimately agreed, that Thompson's employment be terminated.
OFCCP Compliance Evaluations/Desk Audit — I have represented a multi-establishment federal contractor in responding to multiple desk audits conducted by the OFCCP.  Those audits have involved extensive analysis of employment data and responses to follow-up inquiries from the OFCCP, particularly with respect to the employer's compensation system.  I have advised employers on their compliance obligations under OFCCP regulations, have assisted in analyzing their exposure with respect to previous employment decisions, and have recommended changes to procedures and practices going forward.
