Union dues are a fee charged to bargaining unit members by the union and are calculated by the union to cover the costs of the union representation work, including contract negotiation, administration, and disputes. The dues may be a flat rate or a percentage of wages. They may also be used for the purpose of organizing at other employers and for making political contributions. Unions may seek to require that members of the bargaining unit who choose not to join the union pay an "agency fee" (sometimes called "fair-share" fee), typically a small percentage less than full dues, which is calculated by the union.
Unions support themselves through the assessment of union dues or fees collected from bargaining unit members. Although the collection of dues is often facilitated by employers through a dues checkoff card, the money paid in dues must come directly from the employee.
According to the DCLWU’s website, dues will be deducted from employees’ paychecks.
