I'd say there are plenty of happy TeamJQ staff around at the moment.
I'd say ask the same question again in about 8 months and you'd probably get a different answer when all the "This is my dream job" excitement has dwindled.
I'm sorry to sound so pessimistic, but even crew covered under the EBA feel that way at times.
and JQ is just the IATA designator code. Doesn't really need to stand for anything.
IE Jetstar Asia uses 3K, Qantas QF, Virgin Blue DJ.
