This was an obvious and predictable outcome of Obama's policies.
Just about anyone who has managed to get a job with any major employer since Obama was first elected has been hired on as part-time, finding their hours are managed to just under the 40-hour per week range. No benefits and no overtime. This is hugely common and only "experts" with their heads in the sand haven't observed it.
Of course, this is also France's strategy: They've cut the lawful full-work week down to 35 hours. Any business that wants to keep productive has to hire more workers to get the job done. Everyone in France works part time with gov. benefits.
Socialists are the same everywhere.
