The Standard Occupational Classification (SOC) System is a United States government system of classifying occupations.
 It is used by U.S. federal government agencies collecting occupational data, enabling comparison of occupations across data sets.
 It is designed to cover all occupations in which work is performed for pay or profit, reflecting the current occupational structure in the United States.
 The 2010 SOC includes 840 occupational types.
Banjo the Woodpile Cat is a 1979 animated short film directed by Don Bluth.
 It follows the story of Banjo, an overly curious and rebellious kitten who, after getting into trouble for falling from a house to see if he could land on his feet, runs away from his woodpile home in his owners' farm in Payson, Utah by catching a truck to Salt Lake City.
 Produced in a shoestring budget, and created in Bluth's garage, the film took four years to make and it was the first production of Don Bluth Productions, later Sullivan Bluth Studios.
 It had a short theatrical run from December 21 to 28, 1979 at the Egyptian Theatre in Hollywood and the Peppertree Cinema in Northridge as an opening short for the holiday re-release of "The Muppet Movie", but did not appear on network television until 1982.

 Within the revolutionary movement, it opposed the influence of major trade unions and the French Communist Party who intended to contain the revolt and compromise with General Charles de Gaulle.
The Standard Occupational Classification (SOC) system is used by the United States Federal statistical agencies to classify workers into occupational categories for the purpose of collecting, calculating, or disseminating data.

 To facilitate classification, occupations are combined to form 23 major groups, 96 minor groups, and 449 broad occupations.
 Each broad occupation includes detailed occupation(s) requiring similar job duties, skills, education, or experience.

Occupational injustice occurs when occupational rights are violated, such as when people are excluded from meaningful occupations or when unpreferred occupations are imposed upon them thus limiting life satisfaction.
 The construct of occupational rights stems from human rights but focuses on the inherent right of individuals to participate in occupations.
 Through this participation, occupational rights contribute to fulfillment and self-actualization.
