Unions typically have incentives to protect the interests of existing workers, ensure that those in work use their skills adequately and have access to good-qualily training, and see that investments in training are reflected in better-quality Jobs and higher salaries. In the United Kingdom for example, the Trade Union Congress (TUC) established UnionLearn, a network of "learning representatives" who provide a high-profile strategic framework and support for union work on skills development and workplace learning. Unionl earn representatives provide information and advice and encourage employers to sign up to a "skills pledge" that commits them to training their staff to a specific level of qualification or diploma.
