A US appeals court ruled that three former Kelly Services Inc. (NASD: KELYA) employees in Minnesota must pay the staffing firm $72,000 in legal fees after a judge barred them from working for a rival until their noncompete agreements expired. Reuters reported the unanimous three-judge panel on Thursday rejected the workers’ claims that because the judge issued a temporary injunction against them but did not rule that they had violated the agreements with Kelly, the pacts did not require them to cover the company’s legal costs.
