 Also in 2005 , Alaska Airlines contracted out many of its jobs , including ground crew positions , to Menzies Aviation . In some cases this resulted in an almost 40 % decline in wages . This agreement was found to be a violation of union agreements in 2008 and the new ground crews caused enough damage to aircraft in the first year to make the savings negligible . In addition , Menzies contractors gained a reputation of stealing from checked bags after a few incidents in 2007 .
