I wrote about it earlier.
Mother Jones has an article about why the Act doesn't help working families, and it mentions one aspect I failed to cover:
And if the company stiffs the worker on the overtime compensation, the bill prevents workers from complaining to the US Department of Labor, as they can now, and instead forces them to try to find a lawyer who will take up their cause to collect a few hundred dollars worth of back pay, a fairly toothless enforcement measure. The bill, supported by the US Chamber of Commerce, is a backdoor attempt to shield big companies like Wal-Mart from costly lawsuits they've seen stemming from their systematic refusal to pay low-wage workers the overtime to which they're legally entitled.
