While the private sector has added 1.6 million jobs to the economy in the last year, the public sector is shedding 35,000 jobs a month, by one economist's estimation. Weak public-sector hiring may continue as President Barack Obama and Congress have yet to agree on a jobs package that would prevent job cuts by federal, local and state governments. "Revenues are down because the economy is weak. And that’s forcing them [state governments] to cut spending. And the spending they can cut the most easily is workers,” said Rob Shapiro, chairman of economic consulting firm Sonecon.
