Midwest Stock Exchange, Inc. v. N.L.R.B

In Midwest Stock Exch., Inc. v. NLRB, 635 F.2d 1255 (7th Cir. 1980), the court found that an employer discriminatorily enforced its no-solicitation rule by strictly enforcing the rule against union activities but permitting "[s]uch drives as the Crusade of Mercy, collection of blood in a bloodmobile... [on the employer's] premises, the selling of Avon products, Tupperware, boat cruise tickets, raffle tickets, Girl Scout cookies, and a number of other items."
