  11. Job Design Labor Standards People and Work System Aspects © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  12. Follow demand exactly keeps direct labor costs tied closely to production incurs costs of hiring/firing unemployment insurance labor wage premium Hold employment constant maintains a trained workforce incurs costs of idle time when demand is low meeting increased demand when demand is high Labor Planning/Stability Policies © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  13. Productivity in Relation to Annual Turnover Rate © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  14. Determining Policies of Labor Stability Employer policies are partly determined by management’s view of labor costs – as a fixed cost, or as a variable cost. © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  15. Work Schedules • Standard work schedule • five eight-hour days • Flex-time • allows employees, within prescribed limits, to determine their own schedules • Flexible work week • four 10-hour days • Part-time • less than eight hours per day, or an irregular schedule © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  16. Job Classifications and Work Rules • Specify • who can do what • when they can do it • under what conditions they can do it • Often result of union pressure • Restricts flexibility in assignments; consequently restricts efficiency of production © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  17. Job Design • Specifying the tasks that make up a job for an individual or group • Involves determining • What is to be done (i.e., responses) • How it is to be done (i.e., tools etc.) • Why it is to be done (i.e., purpose) • Results in job description • Shows nature of job in task-related behaviors © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  18. Components of Job Design • Job specialization • Job expansion • Psychological components • Self-directed teams • Motivation and incentive systems • Ergonomics and work methods © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  19. Job Specialization • Involves • Breaking jobs into small component parts • Assigning specialists to do each part • First noted by Adam Smith (1776) • Observed how workers in pin factory divided tasks into smaller components • Found in manufacturing & service industries © 1995 Corel Corp. © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  20. Job Specialization Often Reduces Cost • Greater dexterity & faster learning • Less lost time changing jobs or tools • Use of more specialized tools • Pay only for needed skills © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  21. Job Expansion • Process of adding more variety to jobs • Intended to reduce boredom associated with labor specialization • Methods • Job enlargement • Job enrichment • Job rotation • Employee empowerment © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  22. Enriched Job Planning Enlarged Job Present Job Task #2 Task #3 Control Job Enlargement/Job Enrichment © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  23. Planning Participate in a cross-function quality-improvement team Enriched job Task #3 Lock printed circuit into fixture for next operation Present job Manually insert and solder six resistors Task #2 Adhere labels to printed circuit board Control Test circuits after assembly Enlarged job Job Enlargement/Job Enrichment © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  25. Decision-Making Control Planning Employee Empowerment Employee Empowerment © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  26. Psychological Components of Job Design • Individuals have values, attitudes, and emotions that affect job results • Example: Work is a social experience that affects belonging needs • Effective worker behavior comes mostly from within the individual • Scientific management argued for external financial rewards • First examined in ‘Hawthorne studies’ © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  27. Hawthorne Studies • Conducted in late 1920’s • Western Electric Hawthorne plant • Showed importance of the individual in the workplace • Showed the presence of a social system in the workplace © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  28. Hawthorne Studies: Workplace Lighting • Originally intended to examine effects of lighting on productivity • Scientific management proposed that physical conditions affect productivity • Result: Productivity increased regardless of lighting level • Conclusion: Increased productivity was due to workers’ receiving attention © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  29. Hawthorne Studies: Piecework Pay • Examined effects of group piecework pay system on productivity • Workers under piecework system should produce as much as possible • Scientific management assumes that people are motivated only by money • Result: Production less than maximum • Conclusion: Social pressure caused workers to produce at group-norm level © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  30. Self-Directed Teams • Group of empowered individuals working together for a common goal • May be organized for short-term or long-term objectives • Reasons for effectiveness • Provide employee empowerment • Provide core job characteristics • Meet psychological needs (e.g., belonging) © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  31. Self-directed Teams Increasing reliance on employees’ contribution and increasing acceptance of responsibility by employee Empowerment Enrichment Enlargement Specialization Job Expansion Job Design Continuum © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  32. Core Job Characteristics • Skill variety • Job identify • Job significance • Autonomy • Feedback © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  33. Limitations to Job Enlargement/Job Enrichment • Higher capital cost • Many individuals prefer simple jobs • Higher wages are required since the worker must utilize a higher level of skill • A smaller labor pool exists of persons able and willing to perform enriched or enlarged jobs • Increased accident rates may occur • Current technology in some industries does not lend itself to job enlargement and enrichment © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  34. Motivation • Worker performance depends on • Motivation • Ability • Work environment • Motivation is the set of forces that compel behavior • Money may serve as a psychological & financial motivator © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  35. Motivation and Money • Taylor’s scientific management (1911) • Workers are motivated mainly by money • Suggested piece-rate system • Maslow’s theory (1943) • People are motivated by hierarchy of needs, which includes money • Herzberg (1959) • Money either dissatisfies or is neutral in its effect © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  36. Monetary Incentives • Bonuses: Cash & stock options • Profit sharing: Distribution of profits • Gain sharing: Reward for company performance (e.g., cost reduction) • Scanlon plan is most popular (cost reduction.) • Incentive systems • Measured daywork: Pay based on standard time • Piece rate: Pay based on pieces done © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  37. Self-Actualization Use of abilities Self-fulfillment Ego Self Respect Social Group Interaction Job Status Safety Physical Safety Job Security Physiology Food Shelter Maslow’s Hierarchy of Needs © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458

  38. Job Dissatisfiers (Hygiene) Job Satisfiers (Motivators) • Achievement • Recognition • Advancement • Work itself • Responsibility • Personal growth • Company policies and administration • Supervision - technical • Working conditions • Interpersonal relations - supervision • Status • Job security • Salary Herzberg’s Motivation/Hygiene Factors © 2004 by Prentice Hall, Inc., Upper Saddle River, N.J. 07458
