Supporting IUOE

Winmill Software is a firm supporter of organized labor, and we built our eMembership platform exclusively for labor unions like IUOE.

IUOE was founded in 1896 and now has over 400,000 members in over 120 local unions in North America. The IUOE International Training & Education Center, along with over 100 local training and apprenticeship programs, ensure that IUOE members are the safest, most productive, and highly skilled craft workers in North America.

40+ union locals trust eMembership, including IUOE locals. eMembership supports IUOE’s commitments to ensuring protection of prevailing wages on public projects, improving contractors’ competitiveness, and alleviating healthcare costs through coalition building.


Our Process

One size does not fit all! We know that no two unions are exactly alike, and we customize eMembership to work for you – not the other way around. You pick and choose what modules you need, and we customize them to match your exact requirements. ​

No Hardware, No Software, No Hassle

Winmill securely hosts eMembership in our 24/7 high-availability data center, so it is available for you anytime from anywhere. We focus on the hardware, software, operating systems, security patches, system monitoring, bandwidth, backups… to give you the freedom to focus on your core business.

We host hundreds of applications for clients ranging from small local unions to massive commercial banks. Our data center maintains SOC 1 (SSAE18/ ISAE3402), SOC 2, HIPAA, and PCI DSS compliance.

​Welcome to a world where you’ll no longer worry if your server is secure, or if your backup ran last night. Welcome to the cloud. Welcome to eMembership. ​

“The entire staff is very professional. During our weekly meetings, the eMembership staff took their time to understand my ideas and worked hard to implement exactly what we were aiming for. I thoroughly enjoy working with the staff at Winmill. They are a great company and I would highly recommend them.”

“Great membership database! Our Winmill eMembership database is a robust tool that all of our staff uses daily. I was part of the team that researched a number of different options. We decided on eMembership because it came highly recommended by other union reps, and the cost of eMembership was very affordable. We have had no regrets and are very happy with our choice.”

Lydia P., Director of Membership Services, IATSE Local 800

“We liked the discovery process as well as the development and final functionality of the customized software. Great programmers along with a team that really got in tune with our needs. I would highly recommend Winmill’s eMembership software for your business solutions. Professional expertise is what you will experience with this team!”

David F., President, IATSE Local 110

“Our organization, IATSE Local 800, engaged Winmill to create our eMembership database in 2011. This was not a small task due to a merger of 4 IATSE Locals. The technical experts were with us every step of the way, providing expert technical support and training, both on site and virtual. The support did not stop once we were up and running. For the past 10 years, the Winmill team has provided innovations for optimal performance and has offered solutions for our organizations growth and fluid needs. The team is highly responsive and makes us feel like we are their only client. I would highly recommend Winmill software and cannot imagine doing my job without our database and their expert team to support me.”
