Help wanted on teens’€™ summer jobs

Teens with summer jobs are more likely to find themselves behind a counter than in front of a computer. Mayor Thomas M. Menino of Boston is hoping to change that, and he’s calling on the city’€™s newest corporate citizens for help. As he launches his annual campaign for summer jobs for teens today, the mayor is asking Boston’€™s tech and Web companies to make room for high schoolers during the summer break.
