Business of the House (Lisbon Treaty)

After opposing a private Member’s Bill on the issue tooth and claw, the Government were instrumental in ensuring that there was no agreement on a European directive on temporary and agency workers on 5 December last year. I note from the list of topics that there is no session provided to discuss the social and employment aspects of the treaty. Why is that, given the importance attached to those issues on the Government Benches? What day may issues such as the directive on agency workers, or indeed working rights generally, be discussed?
