Flexible working is not just for women with children. It is necessary at the other end of the scale. If people can move into part-time work instead of retirement then that will be a huge help. If people can fit their work around caring responsibilities for the elderly the disabled then again that's very positive.
Yes it's a man's world but that's all right because they're making a total mess of it. We're chipping away at their control taking the parts we want. Some women think it's a difficult task but it's not.
