... the individual is not owed a living of their own choosing!
The individual should have pay and conditions at market rate (or thereabouts) for their job. I have as flight crew and I would suggest that pretty much everyone else in BA has as well, with one group being a glaring exception.
Just explain again why you feel your pay and conditions should be so significantly different to the market rate for your job when "market rate" is good enough for the rest of the company....
