The picture, which was posted on the personal website of a happiness consultant who goes by the name of Mary Ann, features a bare-chested woman in a UPS shirt alongside the caption, "Look at my naughty time from yesterday."
Brian Bates, founder of JohnTV.com, which is dedicated to exposing prostitution in OKC, got his hands on the picture and wrote about it on his website.
"What really shocked me is that a driver would put himself in this position, no pun intended, and then allow the pictures to be posted publicly," Bates said. "He really had nothing to gain and he has everything to lose and not at the time of year you want to be losing your job.”
The picture has since been removed from the website.
According to Bates, a follow-up post on Mary Ann's website described sex with the driver in graphic detail. "She was touting much more explicit photos of this encounter on a version of her web site that is locked away and it's only for members," Bates said.
UPS spokesperson Susan Rosenberg is trying to track down the driver who was in the photos so that he can immediately be terminated.
"It disrespects UPS drivers and customers. This is not behavior we would ever condone for anyone, let alone for our company. We want to assure other drivers and our customers that this will be fully investigated," Rosenberg said.
