My friend Carmen
I actually really like Carmen! I've been playing with her for nearly 6 years and we have a mutual understanding. She can be temperamental at times (then again, us girls get pmt every so often). She needs tlc and a bit of gentle persuasion. I get around 75% of my bids which is more than I can expect, really. As junior crew, you can expect up to 40% satisfaction. If you have issues with Carmen, there should be someone in your scheduling department who can deal with it (in my company you can send a rosta query form to head of scheduling who will then look at it for you and explain what's going on).
I'm glad that I at least have some option as to what I bid for, instead of the old system where you got what you were given (way too many Tripoli's for my liking then). There's always rosta swaps as well, unless you're not allowed to do that kind of thing.
Keep playing with Carmen, try different things, don't give up and most of all, good luck.
