Colorado Right-to-Work Law
Colorado uses a modified Right-to-Work statute. In Colorado, employees can be compelled to become part of a union, as long as the following process is used:
In order for a local union to represent a group of employees, an election among the employees wishing to be represented must take place. If the results of the election favor unionization by a 75% or more margin, a second election must be held to determine mandatory union representation, which only requires a simple majority (51%).
In the event both elections pass with the respective majorities, a clause for compulsory union membership may be included in the union's labor contract, however, it is not required. A company may elect to grant or deny the union's request to include the mandatory membership clause.
