The first meeting of FairPoint and unions representing workers in northern New England since late August has failed to produce a breakthrough.
Both the company and unions representing more than 1,700 striking workers blamed each other for failing to offer a compromise.
The chairman of the unions' bargaining committee said FairPoint seems intent on running the company into the ground by failing to compromise. Likewise, the company accused the unions of making no proposals "and for that reason the impasse continues."
Tuesday's discussion in Boston was arranged by a federal mediator and lasted about an hour.
FairPoint declared an impasse in late August and imposed a contract over two unions' objections. Workers have been on strike for a month in Maine, New Hampshire and Vermont.
