Royal Mail's chief executive Moya Greene publicly supported Cable, stating that the sale would provide staff with "a meaningful stake in the company", while the public would be able to "invest in a great British institution". On 12 September 2013, a six-week plan for the sale of at least half of the business was released to the public; the Communication Workers Union (CWU), representing over 100,000 Royal Mail employees, said that 96% of Royal Mail staff opposed the sell-off. A postal staff ballot in relation to a nationwide strike action was expected to take place in late September 2013.
