OAKLAND (AP) — Bay Area Rapid Transit officials and its two largest unions were meeting on Monday to go over the agency’s estimates of how much a disputed contract provision would cost.

BART and the unions, SEIU Local 1021 and ATU Local 1555, did not plan to hold negotiations over the provision. Instead, the meeting was to focus on BART’s accounting.

At issue is a family leave provision that BART says was erroneously included in the contract language by an unnamed temporary employee in July. The agency says it could cost $44 million over the four-year life of the tentative contract deal. That deal was reached last month and ended a second transit strike.

BART wants the unions to renegotiate that provision.
