My own experience...
Based on the 737 LGW-I mainly just go to work, fly to the SOP's (which as Hand S says do change) and go home again. When things get fun (=difficult) then you just have to make the best of it between the two of you. It ain't difficult in BA, I imagine that things could get harder in other carriers out there!
Right to left seat changes mean (in my case anyhow) that you will stay on the same pay point, and move onto the Capt scale.
I like my job. I am looking forward to flying with the new DEP's (if I move onto the bus...) They WILL have my support when it comes to final salary pension.
