As we noted last month, most private sector employers — regardless of whether they are unionized — will be required, beginning November 14, 2011, to post a notice advising employees of their rights under the National Labor Relations Act. Copies of the poster are now available for downloading and printing on the NLRB website here.

But, don’t put that poster up a second before you have to. A lawsuit filed by the National Association of Manufacturers against the Board seeks to enjoin enforcement of the rule on the ground that it exceeds the Board’s statutory authority. We will keep you posted on any new developments relating to this new rule.
