WRPS - Wave 1:

The survey results are based on telephone interviews with a nationally representative sample of 2,408 adults, 18 years of age and older, who are currently working in private companies or non-profit organizations in the continental United States with 25 or more employees, excluding company owners and their families and upper management. The interviews were conducted from September 15, 1994-October 13, 1994. The survey was conducted by Princeton Survey Research Associates. The sample was split in two (Form A and Form B).

WRPS - Wave 2:

The Wave 2 survey consisted of re-interviews of 801 participants in Wave 1. It was supported by various written materials, sent to all of the roughtly 1400 participants in Wave 1 who there agreed to participate in Wave 2 and read those materials in advance. Telephone re-interviews were conducted between December 6, 1994 and January 24, 1995. Potential Wave 2 respondents were randomly divided into four subsets. Two of these received the material on arbitration, with one having its possible advantages listed first, the other with disadvantages listed first. Theother two received the material on workplace regularory committees, again with one getting advantages listed before disadvantages, and the other the reverse.

In November 1995, the survey was conducted in Canada to 1104 workers. There are 79 variables and 1104 observation in this data set.
