micmclo - most front line staff are in the job for less than 6 months are paid badly and staff turnover is (was) very high and are rather badly treated by customers. Its not the great job that it was many years ago when the now senior management started.
You are correct, the job in a bank isn't held is such a high regard as it used to.
Front line staff are there a lot longer then 6 months, most have been there years and will make it to officer grade some day.
I wouldn't say turnover is that high either.
And yes, calling them yellow packers is offensive!
