Works both ways
Eddy,
If you can learn the art of Revenue Management or even better still, Revenue Accounting in anything less than six months then please go ahead. It is not data imputting - it is protection of revenue and in many cases, it is poorly paid. In BA, much of it has been sent to India so those jobs (and staff) have gone. One incorrect assumption in a particularlar market, peroiod (i.e. Easter) or even individual flight can lose a fortune almost overnight. Some of the highest paid staff at the Locos are the Revenue Management team as they can kill an airline so quickly.
In two airlines I worked for and I am sure that it goes for others, it was commonplace that when a female CC member became pregnant and could no longer fly, they were brought into the office to undertake admin duties. Given the size of one of my employers, that meant a permanent supply of "temps" thus preventing us employing permanent full trained staff. It does work both ways. I know this is a different scenario to the current BA situation but the reverse has happened before.
Chin up - it will be over some time
