The city’s Conflicts of Interest Board on Tuesday announced punishments of three municipal employees who used their jobs for personal gain, including Thomas D. Maloney, a sewage-treatment worker who stole 11,328 pounds of metal materials worth about $13,700 and sold the goods for a profit.

Maloney, who has since pleaded guilty to petty larceny, agreed to pay restitution, resign his post and accept his prior suspension. The person who answered the phone Tuesday night in the office of his attorney Faustian Zapata declined to comment.

Also forced to resign was Edward Ginsberg, a Department of Education analyst who bought clothes, candy and an Amazon Kindle with a co-worker’s government procurement credit card. His attorney’s office referred inquiries to Ginsberg, and he couldn’t be reached Tuesday night.

Melissa Worthy-Smith, a public-health adviser who took her department-issued vehicle shopping at the Green Acres Mall, was fined and suspended for six days. She could not be reached for comment Tuesday night.
