Many businesses have joined the Corporate Alliance Against Domestic Violence which was set up in September 2005. It now consists of 160 businesses representing over two million employees and raises awareness of the issue among managers so they are able to spot the signs of domestic violence to help their employees and maintain the efficiency of their business.
