Unionized Workers Significantly Less Satisfied Than Non-Union Employees With Job Security, Workplace Safety, Supervisor, Recognition, Hours Flexibility

From Gallup, "Union Members Less Content With Safety, Recognition at Work" by Andrew Dugan:

In the U.S., employed Americans who report being members of labor unions are significantly less likely than nonunion employees to say they are "completely satisfied" with six of 13 job aspects. These include workplace safety, recognition for accomplishments, flexibility of hours and job security. In only one job aspect, employer-provided health insurance, are union workers significantly more likely than nonunion workers to say they are completely satisfied.
