If you are a supervisor as defined by the National Labor Relations Act NLRA), you would be excluded from the bargaining unit and therefore not eligible to vote or be represented by the union.  The NLRA defines a supervisor as someone who has the authority to do at least one of the following: hire; transfer; suspend; lay off; recall (from layoff); promote; discharge; assign; reward; discipline; “responsibly” direct other employees; or adjust grievances, and that such actions require “independent judgement.”  If you think you might be a supervisor, feel free to reach out to us at columbiapostdocunion@gmail.com and we will look into your situation.
