Four years ago today President Obama signed the Lilly Ledbetter Fair Pay Act, with Lilly Ledbetter, who suffered 20 years of pay discrimination while doing the same work as men at her Goodyear Tire & Rubber Co. factory, looking on.

Now, she is urging people to call on Congress to pass the recently reintroduced Paycheck Fairness Act, calling it “the next step.”

My Fair Share is a cross-post from Working America’s Dear David workplace advice column. David knows you deserve to be treated fairly on the job and he’s available to answer your questions, whether it is co-workers making off-handed comments that you should retire or you feel like your job's long hours are causing stress.

Question:

What can you do about not being paid a fair wage for the work you do? I make a lot of money for the company I work for feeding a robot up to 4,000 packages per hour. How do I get some of the money I make for the company through high production paid to me?

Ninety-two years ago yesterday, U.S. women won the right to vote.

The Indiana State AFL-CIO mentioned in an e-mail yesterday, Rose Schneiderman, who headed the Women’s Trade Union League, explained in 1918:

We want to tell our Senators that the working women of our State demand the vote as an economic necessity. We need it because we are workers and because the workers are the ones that have to carry civilization on their backs.

The anniversary is a good time to reflect on how women would fare under a Romney-Ryan administration.

Today, as equal rights advocates mark Equal Pay Day to remind the nation that women are paid  just 80 cents for every dollar men earn, Sen. Tom Harkin (D-Iowa) introduced the Fair Pay Act of 2011 that would ensure that employers provide equal pay for jobs that are equivalent in skill, effort, responsibility and working conditions.
