Four female sales representatives have sued pharmaceutical group Sanofi-Aventis for sexual discrimination in a $300m class action lawsuit...[T]he women allege that they were barred from promotion opportunities, received lower pay rises than their male colleagues and were subjected to sexually abusive working environments. The suit seeks class action status, with potentially larger implications for the 8,000 US sales personnel of the French drug maker. Marc Greene, a spokesman for Sanofi-Aventis...said that the company was confident that “the suit lacks merit, and that all of our employees are treated fairly and in compliance with all applicable federal and state laws”.
