There is an article published today http://bit.ly/TZqrmV about women who anticipate divorce, working longer hours. In this economic climate, divorce is an added stress on the household budget, even more so than normally.
Women who historically have not been the primary earner feel in those circumstances that they are going to be considerably worse off once they are separated. In a bid for some financial independence and autonomy, they may be driven to increase their workload. In a country where jobs are contracting rather than expanding, it seems unlikely that this would be easy, but if this research is correct, then it is another indicator, if ever we needed one, that divorce impacts all aspects of our lives.
