FILE - This Sept. 10, 2012 file photo shows Striking Chicago Public School teachers picketing as Mayor Rahm Emanuel visits with students taking part at the Safe Haven program during a teachers strike in Chicago. A threatened strike in 2019 by Chicago teachers would carry on the city's historically significant role in education labor disputes, including the 2012 strike cited by teachers around the country as inspiration for walkouts and other protests in recent years. That seven-day strike was a dramatic test of the Chicago Teachers Union's effort to force expanded negotiations into social issues beyond the typical give-and-take over pay and benefits. (AP Photo/M.

FILE - In this Oct. 4, 2019 file photo, Democratic presidential candidate Sen. Elizabeth Warren, D-Mass., speaks at the SEIU Unions For All Summit in Los Angeles. For 41 years, federal law has banned pregnancy discrimination in the workplace. But the stories tumbling out this week show it’s far from eradicated. Prompted by Warren’s claim that she was forced out of a teaching job in 1971 because she was pregnant, scores of women have shared similar stories on social media. Police officers, academics, fast food workers, lawyers, flight attendants and others say they hid pregnancies on the job or during interviews, faced demotion or demeaning comments and were even fired after revealing a pregnancy.(AP Photo/Ringo H.W.
