Misuse of City Cellphone Costs Worker Her Job She spent almost a decade working for the city agency that specializes in telecommunication technology, yet it was a flagrant violation of the city's cellphone policy that brought about her resignation. Shirl Mayo, a senior administrative coordinator for the Department of Information Technology and Telecommunications, used her city-owned BlackBerry to make nearly 20,000 minutes" worth of personal calls over 10 months, racking up $3,316 in charges, the city's Conflicts of Interest Board said on Wednesday. That comes out to about an hour a day. Ms. Mayo, who has worked for the city for 27 years and who was earning $53,000 a year in 2010, according to findthedata.org, a Web site that collects information from publicly available databases, knowingly failed to pay the charges, the conflicts board said. Public servants are not allowed to use city vehicles, telephones, computers, or e-mail accounts for private use. Ms. Mayo is not being required to refund the money.
