The Equal Employment Opportunity Commission has sued Mannatech Inc., alleging in recently filed court documents that the local multilevel marketing firm violated federal law by firing an employee who had a disability.

The suit, filed last week in federal district court in Dallas, alleges that Mannatech engaged in 'unlawful employment practices' by firing the worker, Jill Roberts, from her job in a call center because Roberts is 'disabled, regarded as disabled or because she has a record of a disability.'

According to the EEOC's complaint, Roberts also asked for a 'reasonable accommodation to use the restroom on an as-needed basis.' That request was denied, the EEOC's court records allege.
