And an opinion poll commissioned by the government shows that the most significant factor in the increase is a desire among women for a better balance between work and family life. The biggest motivation for doing it alone—according to 70% of those polled--was to be able to work more flexibly. Three out of four said that their work and family life balance was better when they ran their own business.Tanya Rostron, a mum of two children, employs 11 people at her firm, which supplies water coolers throughout the East Midlands.
