That clearly is not true. People's needs and society's needs do not start and end with what they do at work. The balancing act of being a working carer, whether of children or other dependants, can become a major issue for people. We must also ask ourselves whether it is in employer's interests for people to work excessive hours. There are health risks.
Accidents are more likely.
Absenteeism may rise. People may feel compelled to leave jobs because they simply can't manage time demands which may suit some, but are unlikely to suit all. It is more likely that women will suffer from this than men. The Government recognise that there is a major cultural issue to be addressed. This is a false dichotomy we work and live.
