(Bloomberg News) Verizon Communications Inc. will pay $20 million to settle a U.S. suit over unlawful policies for disabled workers, the Equal Employment Opportunity Commission said in resolving its largest discrimination case.

Employees of New York-based Verizon and 24 subsidiaries were disciplined or fired when they needed more time off than allowed by the company's leave policies, according to a statement today from the commission that oversees U.S. employment discrimination laws.

Verizon, the second-largest U.S. telephone company, had a policy that set a maximum number of absences for employees, the agency said in a statement. The company refused to make exceptions for disabled workers who needed "reasonable accommodations" in order to work, according to the statement.

"Hopefully this nationwide decree will further public awareness of the importance of engaging in an individualized interactive process to determine whether a disabled employee must be accommodated" under U.S. laws, P. David Lopez, the agency's general counsel, said in the statement.

The settlement gives Verizon "clearer guidance from the EEOC regarding when it may be appropriate to provide additional leave as a reasonable accommodation under the Americans with Disabilities Act," according to a company statement. "This was previously lacking and was a significant factor in Verizon agreeing to settle."

The agreement applies to union-represented employees in the unit that provides wireline phone service, according to the company's statement. The ADA prohibits discrimination based on disability.
