Concept:Trade unions justify wage increases through the employer’s ability to pay, workers’ productivity, or market conditions that allow higher costs to be passed on.
Explanation:Higher company profit means the business can afford to pay its workers more.
Increased worker productivity shows that employees are adding greater value to output.
If the commodity produced is essential, its demand is relatively inelastic, so firms can pass higher wage costs to consumers.
Having high qualifications alone does not directly increase a worker’s current contribution or the employer’s capacity to pay.
Wages are generally linked to actual work output and profitability, not only to certificates or degrees.
Answer:C. members of the union have high qualifications
