Wobbly Economy and Obamacare Push Employers To Hire Part-Time Workers

Businesses want flexibility and lower costs

U.S. businesses are hiring at a robust rate. The only problem is that three out of four of the nearly 1 million hires this year are part-time and many of the jobs are low-paid.

Faltering economic growth at home and abroad and concern that President Barack Obama's signature health care law will drive up business costs are behind the wariness about taking on full-time staff, executives at staffing and payroll firms say.

Employers say part-timers offer them flexibility. If the economy picks up, they can quickly offer full-time work. If orders dry up, they know costs are under control. It also helps them to curb costs they might face under the Affordable Care Act, also known as Obamacare.
