I can fully sympathise with your predicament CPB. City Flyer pilots are the latest in a long line to have their family lives severely disrupted by BA mismanagements feeble attempts to cut costs.
In reality few if any of these attempts have actually saved them anything. In most cases, if not all, the disruption caused to those involved has only added to BAs overall costs. I am thinking here of what happened to Highland Division, then later to the Scottish mainline base, and finally to Manchester and Birmingham.
In the case of Manchester and Birmingham I understand that a good business case was put forward for these bases to continue, but those making the decision chose to ignore it because they "had a feeling" that closure was best.
I wonder if they realise the cost of having disgruntled pilots? I very much doubt it.
