The U.S. Equal Employment Opportunity Commission (EEOC) announced that a lawsuit has been filed against a construction materials manufacturer for religious discrimination against a truck driver.

In a June 4 statement, the EEOC said that a suit was filed against CEMEX Construction Materials Florida, LLC, for violation of the Civil Rights Act of 1964.

Officials say that a female truck driver who is an Apostolic Christian asked CEMEX for permission to wear a close-fitting skirt over her work pants as an accommodation for her religious beliefs. This request was denied due to a company policy that does not permit loose-fitting clothing.

“The employee only wore close-fitting skirts over her work pants and was in compliance with company policy. Ultimately, the company forced the employee to choose between wearing a skirt or losing her job. The employee chose to continue wearing a skirt, which led to her termination,” the EEOC said.

The EEOC argues that CEMEX violated federal law which requires employers to make reasonable accommodation for an employee’s religious observance or practice unless doing so would cause an undue hardship.

“Federal law prohibits discrimination by employers against their employees’ sincerely held religious beliefs,” EEOC Tampa Field Office Director Tamra Schweiberger said. “Employers must not make their employees choose between observing their religion and maintaining their livelihoods where, as here, there is no undue hardship to the company.”

EEOC Regional Attorney Kristen Foslid added, “This is the Miami District Office’s second lawsuit within a month alleging religious discrimination. Employers should take notice that the EEOC will vigorously investigate, and where necessary, litigate, claims of religious discrimination in the workplace.”
