Serving North Dakota and Western Minnesota for over 50 years

If you have worked in the insulation industry for several years or are just getting started Local 133 may be able to help you. Local 133 continually seeks insulators with all levels of experience for work opportunities throughout the territory.

Local 133 offers membership opportunities through the apprenticeship program and the applicant mechanic program. Once an application is completed it is kept on file for future opportunities. Workers with limited experience in the trade may apply to the apprenticeship program. The JAC takes new apprentices into the training program regularly. Workers with extensive experience in the trade may be placed in the applicant mechanic program. The applicant mechanic program is designed to ensure all workers have training in all facets of the insulation industry and also to give credit where credit is earned.

If you would like to be part of an organization dedicated to ensuring all workers equality, justice, and dignity in the pursuit of earning a living wage call Nate Geurts at (701) 891-2014 or e-mail about joining.
