Women filing discrimination lawsuits against Walmart are nothing new. Walmart firing people for questionable and controversial reasons is also nothing new. Now a woman is suing the low-wage retail giant, saying she was fired after complaining about discriminatory treatment. Specifically, Rebecca Wolfinger says her boss told her she had to “choose between her career and her kids.”

Wolfinger’s suit focuses on what she claims was her mistreatment while working as a shift manager. She was being required to work seven days a week when she received the “career or kids” threat, she contends.

Other male shift managers weren’t on a seven-day work schedule, Wolfinger claims. Her February 2012 firing occurred after she reported her boss’ comment to a company human resource officer, the suit states.

Wolfinger was officially fired, she says, for selling Pampered Chef outside of work—but coworkers who engaged in similar activities weren’t fired. And of course a sophisticated company like Walmart doesn’t admit to having fired someone for complaining about illegal discrimination.

Several years ago, 1.5 million women who worked or had worked at Walmart attempted a class action lawsuit against the company, only to have the Supreme Court say that “[e]ven if every single one of these accounts is true, that would not demonstrate that the entire company operate[s] under a general policy of discrimination.” That’s despite evidence like this:

Many female Walmart employees have been paid less than male coworkers. In 2001, female workers earned $5,200 less per year on average than male workers. The company paid those who had hourly jobs, where the average yearly earnings were $18,000, $1.16 less per hour ($1,100 less per year) than men in the same position. Female employees who held salaried positions with average yearly earnings of $50,000 were paid $14,500 less per year than men in the same position. Despite this gap in wages, female Walmart employees on average have longer tenure and higher performance ratings.

Doubtless all just a coincidence, though. Just like Rebecca Wolfinger was coincidentally fired for something that other workers did after she reported being discriminated against.
