Many part-timers are facing a double whammy from President Obama's Affordable Care Act. The law requires large employers offering health insurance to include part-time employees working 30 hours a week or more. But rather than provide healthcare to more workers, a growing number of employers are cutting back employee hours instead. The result: Not only will these workers earn less money, but they'll also miss out on health insurance at work. Consider the city of Long Beach. It is limiting most of its 1,600 part-time employees to fewer than 27 hours a week, on average. City officials say that without cutting payroll hours, new health benefits would cost up to $2 million more next year.
