In October 2000, the Government supported the European Directive on Equal Treatment and committed to implementing age legislation by 2006. A 6-year implementation period was agreed to allow time for the preparation of clear, workable and beneficial age legislation, formulated in close consultation with individuals, employers and expert groups. The government is also engaged in tackling age discrimination by actively promoting the non-statutory Code of Practice on Age Diversity in Employment.
