That this House is alarmed and concerned to learn from the Information Commissioner's report that the blacklisting of trade union members is widespread in the construction industry; condemns the major construction contractors who subscribed to the Consulting Association and also provided it with information about workers and employees; notes that many of the companies who donated to the Consulting Association are currently engaged on publicly-procured work projects worth billions of pounds; considers that there may be legal implications where for example an employee or worker believes they were dismissed because they were on the list and requests that the Information Commissioner gives a reasonable time for people to make the appropriate checks; and calls on the Government to enact immediately legislation to prohibit the compilation of a blacklist containing the details of workers and employees with a view to them being used by employers or employment agencies to discriminate in relation to employment and to make it a criminal offence for an employer to commission such information.
