His response that it was because it put union people to work. : The Union is my Shepherd, I shall not work. It maketh me to lie down on the job; It leadeth me beside the still factories, It restoreth my pay-cheque. It leadeth me in the path of idleness for its name sake. Yea, tho' I walk through the Valley of the Shadow of unemployment I shall fear no hunger: for it art with me, its representative and his staff, they comfort me. It preparest a table before me in the presence of my bosses: it anointest my head with beer, my cup runneth over. Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Union for ever.
