Recently, we pointed out that the effort by the National Labor Relations Board to impose on all employers an obligation to post notices about union organizing rights remains stalled. That article resulted in some questions about whether federal contractors and subcontractors are still required to post a notice about union organizing. The posting obligation for federal contractors and subcontractors is based on Executive Order 13496, which was signed by President Obama in 2009 and took effect in June, 2010. That obligation remains in effect for federal contractors and subcontractors. It is not changed by the NLRB’s stalled effort to extend the obligation to all employers.
