European legislation (Council Directive 2002/14) that provides a framework for minimum standards of information and consultation at national level where 50 or more persons are employed in an undertaking. In the UK, the directive was implemented by the Information and Consultation of Employees Regulations 2004. Initially only undertakings employing at least 150 employees are covered; those employing at least 100 were covered from April 2007 and those employing at least 50 from April 2008. The Regulations, which are enforced by the Central Arbitration Committee, call for the provision of an information and consultation procedure, either at the initiative of the employer or request of the employees. Agreements concluded prior to the coming into force of the Regulations (April 2005) are not covered.
