After a voluntary layoff program fell short of its goal late last year, Aol has started the process of handing out pink slips to between 1,200 to 1,400 employees worldwide. In December, AOL sought up to 2,500 employees willing to voluntarily walk away from their jobs. However, only 1,100 employees took AOL up on its offer, AOL spokeswoman Tricia Primrose said Monday via e-mail. The company wanted to trim a third of its 6,900 staff.
