There has a phenomenal race to the bottom in terms and conditions in ground handling meaning meaning that motivated and able staff won't stay as the conditions are awful. BA and Midland used to self handle with staff who bought into the brand and had some judgement and latitude. Nowadays the market is so competitive that they simply dress third parties up in uniforms, pay them peanuts and don't allow them to stray one inch from their SLAs. Like cabin crew, it was a career choice for many, however newcomers to market without these legacy costs meant this was uncompetitive. Result everything outsourced, able and loyal people left and well you can see the results as Menzies, Servisair, Swissport and DNATA prostitute themselves ever lower.
