UPDATE 3:00 p.m. PST: Republican Indiana Gov. Mitch Daniels has signaled that Republicans should drop the right-to-work bill.

Daniels told reporters: "he expects House Democrats will return to work if the bill dies."

Democrats in Indiana's House of Representatives fled to Illinois and Kentucky on Tuesday, blocking the House from consdering legislation that would curtail the power of unions.

Only two or three of the 40 Democrats showed up for business in the House on Tuesday.

Indiana's House Democrats pulled the ploy out of the playbook of Democrats in Wisconsin's State Senate. Legislators in Wisconsin have been in undisclosed locations throughout Illinois since Thursday. By holding out, the Democrats are preventing Republican majorities from achieving the quorum necessary to take action on legislation.

The House is expected to call roll again Tuesday afternoon at about 11 a.m. PST.

At Indiana's capitol building, hundreds gathered inside and outside to protest the taking of any anti-union measures. According to an Indiana reporter, they chanted, "Ditch Mitch [Daniels, Indiana's governor]" and "Save our Families." 

Indiana's right-to-work legislation would bar unions from forcing non-union members at a company to pay dues or join a union as part of its collective bargaining agreement with the employer. 

The nationwide fight over labor unions erupted last week when Wisconsin Gov. Scott Walker said preventing unions for collectively bargaining pension and health benefits would help the state out of financial troubles.

Indiana Gov. Mitch Daniels, a Republican, has yet to fully support the anti-union legislation. He's previously said he would like the state Legislature to focus on some of his major priorities, including overhauling the state's education system. Daniels is a potential candidate to run for president next year.

Democrats in Indiana last walked away from the Legislature in the mid-1990s during a redistricting debate.
