October 21, 2014 3BL Media - Marks & Spencer (M&S) has scaled up its use of mobile technology in the supply chain to poll 64,230 workers across 46 manufacturing locations in 5 countries (China, India, Bangladesh, Sri Lanka and the UK) – exceeding its target of 22,500 workers in 30 factories by more than double.br br Mobile survey data revealed interesting differences in knowledge among workers in areas such as workplace communications. For example, more factory management responded affirmatively to the question “Is there a way workers can submit a written complaint when they have a work related-problem?” than workers did. M&S will use this data develop training programs on Workplace Communications and align the company’s business practices with worker needs.
