NEW YORK ( TheStreet) -- The job market did not witness the same recovery the overall economy did in 2010, and remains the biggest wildcard to continued improvements in 2011. The year started with the national jobless rate at a whopping 10%. That number tapered a bit, dropping to 9.5% midway through 2010, before rising again to 9.8% in November. While those who have jobs are more confident that they will keep receiving a paycheck, there doesn't seem to be much of a reprieve for those still unemployed. What has seen growth within the labor market is temporary hiring, which has increased across all sectors, not just among retailers beefing up their staff for the holiday season. It shouldn't come as a surprise that businesses handed out pink sheets at a steady rate throughout the year, as companies looked to cut costs and create more efficient operating models. And while a chunk of excess fat has effectively been cut at most companies, layoffs are expected to continue at the same pace. Overall, most economists don't foresee any significant boost in hiring until well into 2011. Here's a look at companies that laid off workers in 2010. Here, then, is a look at those corporations that have laid off workers since the beginning of the year.
