In the 1970s, the Teamsters Union claimed to have 2.2 million members.
Fast forward to today and the Union has lost hundreds of thousands of members, down to about 1.2 million members.
Fewer members means less dues money, so in recent years the Teamsters Union has been recruiting everyone - parking attendants, blood collection workers - to increase membership.
The Teamsters Union is desperately trying to increase its membership through organizing campaigns. The Union filed 3,692 representation petitions for election with the NLRB in the last 10 years. However, the Teamsters wound up winning just just 46.6% of the time.
And rather than adding new members, the Teamsters Union has been involved in 700 decertification petitions since 2014, where union members decide whether to kick out the union. The Union was only able to win 16.9% of the decertification petitions filed, again not a good sign for a struggling union.
