No union represents more part-time workers better than the Teamsters, who have a proven track record of strength for part-time workers. The Teamsters Union represents the interests of full-time workers and part-time workers. For example, more than half of the 250,000 Teamsters at UPS are part-time employees. The part-time workers at UPS receive the same excellent health, welfare and pension benefits and the same protections that full-time employees enjoy. Both full-time workers and part-time workers are covered by the National Master UPS Contract, the strongest contract in the package-delivery industry. Part-time UPS employees enjoy full-time benefits. Many of the other 1.4 million Teamsters are part-time, including workers at the newly organized UPS Freight, who also have strong protections through strong Teamster contracts.
