Although it might be argued that non-unionization is just the reverse of unionization so that all attempts to model the individual’s decision to unionize apply also to non-membership, in empirical work with cross-sectional data there is some difference between identifying the factors associated with union membership at a certain point in time and the factors that may have influenced individuals’ propensity not to join a union over the past ten or twenty years.
