HARRISBURG — Republicans on a House panel advanced two bills Tuesday that would require proposed contract agreements for public employees and an analysis of their cost to be made public before they are approved by the employer and employee unions.

Members of the House State Government Committee voted along party lines to send the bills to the full House floor after about two hours of discussion. The Senate passed similar versions of the bills along party lines last month.

Democrats charged that the bills are anti-union measures that would disrupt the collective bargaining process and may violate the state Right to Know Law.

The bills are “quite simply an attack on organized labor,” said Rep. Brian Sims, D-Philadelphia.
