Before trucks filled city streets and highways, horses did the hauling. The workers who drove those horse-drawn wagons were called teamsters, and they carried coal, milk, ice, beer, and building materials to homes, shops, and construction sites. Communities depended on that work every day, yet the drivers themselves had little say over their pay, hours, or working conditions.
As the trade grew, those drivers began to organize. In 1903, two rival drivers' unions merged to form the International Brotherhood of Teamsters, a national union built on the collective strength of transportation workers. Teamsters union history follows that path, and the horses on the Teamster emblem still honor the workers who started it.
More than a century later, transportation remains a strong part of the union workforce. The U.S. Bureau of Labor Statistics reports a 13.6% union membership rate in transportation and warehousing for 2025, among the highest of any industry.
To understand what a teamster was, picture a busy street filled with horse-drawn wagons. Early teamsters drove teams of horses and mules through crowds, mud, and snow to reach shops and jobsites.
Bakeries relied on deliverymen, while breweries needed beer wagon drivers. Meanwhile, gravel haulers brought materials that construction crews needed before they could start work.
Handling those loads took strength, patience, and skill with horses. Drivers often faced irregular work and low wages despite those demands. Through teamster unionism, they organized to negotiate better pay, shorter hours, and clearer working conditions.
The International Brotherhood of Teamsters describes a demanding routine in 1900. Drivers typically worked 12 to 18 hours a day, 7 days a week, for an average wage of $2 per day. Even after working those long hours, drivers could still lose pay when customers left bad accounts or a shipment went missing.
Early teamsters often bore the risks and uncertainty of the work themselves.
These working conditions shaped early union organizing. Drivers sought shorter hours, fair pay, and an end to charges for losses beyond their control.
These disputes concerned wages, hours, and responsibility for business losses, issues that workers address through collective bargaining.
As drivers looked for a way to act on those demands, their first national union took shape at the close of the 1890s. The American Federation of Labor chartered the Team Drivers International Union in 1899, with headquarters in Detroit. However, its membership rules allowed owners with up to 6 teams to join.
This created a built-in conflict of interest. Owners were focused on securing higher hauling rates from customers, while drivers wanted higher wages and better working conditions. When hauling rates increased, there was no guarantee that drivers would see a corresponding increase in their pay. That tension came to a head three years later.
At the 1902 convention in Toledo, Ohio, Chicago delegates failed to win the changes they wanted. They then formed the Teamsters National Union of America, which excluded owners who hired other drivers.
The new union adopted an emblem that showed a horse's head framed by a horseshoe, a symbol that tied its identity directly to the animals its members drove every day.

Membership grew beyond 18,000. The union also won shorter days, an end to Sunday work, and extra pay for early and late hours. These agreements addressed drivers' demands for shorter schedules and compensation for work outside regular hours. Yet with two rival unions competing in the same trade, drivers remained divided at a time when they needed to stand together.
Within a year, ending that division became a priority for the wider labor movement. Samuel Gompers, leader of the American Federation of Labor, urged the rival unions to settle their differences. In August 1903, representatives met in Niagara Falls, New York, to negotiate a merger.
The Niagara Falls merger established a single national union and revised the membership and funding rules that had divided the organizations.

The per capita tax was a fee that locals paid to the union for each member. The lower rate helped both sides agree to the deal.
Cornelius Shea became the first General President, and the new union began with roughly 50,000 members. Unity gave the drivers a stronger voice, but their first major test came only two years later.
In 1905, the new union supported the Montgomery Ward strike in Chicago. The dispute lasted more than 100 days, took 21 lives, and cost about $1 million before the strike failed. The defeat marked a major setback in the union's early years.
That setback opened the way for new leadership. In 1907, Dan Tobin of Boston's Local 25 won the presidency, and he went on to lead the union for 45 years.
Under Tobin, the Teamsters expanded their membership among gravel haulers, beer wagon drivers, milk wagon drivers, and bakery deliverymen. The union also supported organizing women. In 1912, convention delegates refused entertainment from non-union employees as an expression of support for organized labor.
As membership broadened, the vehicles those members drove were also beginning to change.
New York's building trades show how transportation changed. In 1903, the national union chartered two building material locals: Local 654 and Local 60.
Local 654 represented 700 members in Manhattan and the Bronx, while Local 60 represented 200 members in Brooklyn. As motor trucks replaced more wagons, drivers needed a union that understood the changing trade.
After those earlier locals dissolved, Teamsters Local 282 received its charter in 1915 as the Building Teamsters Union.
Although motor trucks changed the trade, the union still has a direct link to its horse-drawn roots. Teamsters Joint Council 16 still includes the carriage drivers who work in Central Park. That living connection between past and present carries real meaning for members today.
The pay and working-hour provisions in union contracts reflect generations of organizing, strikes, and bargaining. Teamster history records how drivers challenged long schedules, low wages, and charges for business losses. Their experience forms part of the wider labor movement and helps explain the purpose of protections members negotiate today.

It meant a driver who hauled goods with horses or mules. The name stayed as trucks replaced wagons and workers from other trades joined.
The two rival unions merged in August 1903 at Niagara Falls, New York. Members chose Cornelius Shea as their first General President.
Typical days lasted 12 to 18 hours in 1900, with work across all 7 days. Drivers earned about $2 per day and also faced charges for lost goods or unpaid bills.
Drivers felt the rules gave team owners too much say in the union. Chicago members formed a rival group in 1902 before the groups reunited in 1903.
Yes. Joint Council 16 includes Central Park carriage drivers, so the union retains a direct link to its original trade.
