Inside IAM

The International Association of Machinists and Aerospace Workers (IAM) is an AFL-CIO/CLC trade union made up of a multitude of local lodges that represent union members in certain geographical areas.

The story of the IAM’s campaign to unionize the Delta Air Lines flight attendants is a cautionary tale of how a union can misuse your personal information for its own gain. Know the facts before you consider signing a IAM Union Authorization Card.

A federal judge recently ordered IAM mechanics at American Airlines to stop an illegal work slowdown that has caused tens of thousands of flight delays and cancellations this summer. Is this the type of organization you would trust to represent you with integrity?

Calculate your union dues

Did you know that if the union is voted in, the union will ask you to pay dues and other fees?  In some states, you may have to pay dues or fees to the union to keep your job.

It’s true. If the union contract includes a union security clause – common language included in union contracts – you may be required to pay union dues or fees as a condition of your employment. This means that the union could demand that you be fired if you fail to pay union dues

Every union is different, but most unions set their fees as a percentage of an employee’s pay every month. The more you make, the more you pay the union. (The union sets the dues rate and decides when to increase dues.) Consider how that would add up over the course of a year – or your career.

Union dues/month
Union dues/year
Annual salary less union dues

Only the union determines how much members will pay in dues. Dues were calculated according to the formula in IAM Local Lodge 47 bylaws and does not include or assume regular union dues increases, which occur frequently. They also assume that your annual salary is the weighted average of the bargaining unit, and that you are a full-time MFLC. If you are not a full-time employee, your union dues may be less. As always, calculations are approximate. Any differences in published dues rates may be due to rounding.
