Ah, how soon we forget. Just a year ago, American workers were fretting about job security, with many convinced they could be laid off at any moment. A year later, for the most part, that collective concern has vanished.

So says a Gallup poll of American workers. Gallup asked adults with jobs if they were worried about being laid off in the near future. Last year, 29 percent said yes, they did have that concern. This year, the percentage fell to 19 percent.

"This marks a return of worker confidence to the upper end of the range Gallup saw in the years prior to the financial collapse in late 2008. Workers' concerns about maintaining their current level of benefits and compensation have also eased, though they remain higher than pre-2008 levels," Gallup said in a release.
