The movement of labour from one grade to an entirely different grade is an example of?

Step 1: Analyze the question The question asks about labour moving from one grade (level) to an entirely different grade. The key word is grade, which refers to a level or rank in a job hierarchy, such as a junior clerk becoming a supervisor or manager.

Step 2: Concept: types of labour mobility

• Geographical mobility: movement of labour from one place or location to another, such as from Kano to Lagos.
• Industrial mobility: movement from one industry to another, such as from farming to manufacturing.
• Horizontal occupational mobility: movement from one job to another job of the same level or grade, such as a carpenter becoming a bricklayer, both skilled workers.
• Vertical occupational mobility: movement from one job up or down to a different grade or level, such as a teacher becoming a headmaster, or a clerk becoming an accountant.

Step 3: Apply to the question

• Movement to a different grade means a change in level, which is vertical occupational mobility.
• Option D is about location, and option A is about industry, so neither fits.
• Option B involves staying at the same grade, so it does not fit either.

Step 4: Answer The correct option is C. vertical occupational mobility.

Exam tip: Think of a ladder. Vertical means up or down the ladder (promotion or demotion), while horizontal means sideways at the same level. Whenever you see "grade", "rank" or "level", think vertical.
