There’s no such thing as free porn.

Time Warner Cable has been socked with a $2 million lawsuit by a former employee who says it ignored his religious complaints about his colleagues watching porn on company time.

In papers filed in Manhattan Supreme Court, Keith Reid said he walked in on a construction supervisor at the firm’s Park Slope office watching pornography in February of last year.

“This made plaintiff very uncomfortable, as watching pornography is against his religious belief as a Christian,” the suit says. He complained to HR, but saw another person doing the same thing a month later. His complaints again went nowhere, the filing says.

Reid caught co-workers “watching pornography on approximately 10 different occasions,” the suit says.

Those employees apparently weren’t disciplined, but Reid was, the suit says.

He was suspended and then fired in retaliation for his complaints, it says.

A rep for Time Warner declined to comment.
