There have been a significant number of recent developments that show our labor law in a period of major transition. All of the matters listed below, and more, will be addressed in the forthcoming 2011 Supplement to Cox, Bok, Gorman & Finkin's Labor Law, 15th edition. The coverage of these up-to-the-moment issues in this 2011 Supplement -- through thoughtful notes and questions -- will assure that the instructor will be aware of the latest developments (through mid-summer 2011) and that student involvement will be at the cutting edge. The important new developments covered in this supplement include: Issuance of NLRB complaint against Boeing Company for allegedly discriminatory decision to open new production line in South Carolina rather than Washington State, and potential remedy of opening new line in Washington. Coercion and discrimination for monitoring of and discipline for employee use of Twitter and other electronic social media to communicate concerning working conditions. Proposed NLRB regulation to simplify and expedite representation-election procedures. Preemption or validity of state law invalidating contracts (including authorization cards) between minors and unions. NLRB invitation to file amicus briefs concerning appropriate bargaining units in non-acute health-care facilities, which has provoked a committee request from the House of Representatives for massive amount of related Board materials. Remedial innovations, including electronic posting of remedial notices.
