Telecom alleges employee leaks cost it hundreds of thousands of dollars.

A fast-growing Quincy telecom firm has sued one of its former employees, alleging that the sales representative leaked confidential client data costing the company hundreds of thousands of dollars in lost revenue.

Granite Telecommunications filed a complaint in Boston federal court last week against Stephen Levee, a former employee in Granite's Atlanta office who was fired last month, and Telesource Consulting LLC, a firm that Granite claims was using the information to divert existing and potential customers away from Granite.
