Servisair part-time contracts usually work out, if on a part-time basis, at between 20-25 hours a week minimum. They will ask you to be flexible in working these shifts, and when they mention 38 hours, it usually means over-time which in the busy summer months is often enforced. As has been mentioned in another post of yours, it's all about flexibility. Whilst Servisair are often notorious for being like slave-drivers for new recruits, if you're prepared to show you're flexible, often the management are willing to work the same way. I would definitely go for it.
