Labour Cost Control: Wages, Efficiency, Idle Time & Overtime

Labour Cost: Definition and Importance

Labour cost is the total expenditure incurred by an organization on its workforce to produce goods or services. It includes:

• Basic wages/salaries
• Bonus, incentives, and allowances
• Provident fund, gratuity, and other statutory benefits
• Costs of idle time, overtime, and labour turnover

Why Control Labour Costs?

• Labour is often the second-largest cost after materials in manufacturing.
• Poor control leads to profit erosion (e.g., a Kathmandu garment factory paying for unproductive hours).
• Helps in pricing decisions, budgeting, and efficiency improvements.

Components of Labour Cost

Labour costs are classified into direct and indirect categories:

1. Direct Labour Cost

• Directly traceable to a specific product or job.
• Examples:
  • Wages of tailors in a garment factory.
  • Salaries of drivers delivering goods for Daraz.

2. Indirect Labour Cost

• Not directly traceable to a product but necessary for operations.
• Examples:
  • Factory supervisors’ salaries.
  • Cleaning staff wages in a hospital.

Methods of Labour Cost Control

1. Timekeeping and Attendance Control

• Punch-in/punch-out systems (e.g., NTC employees using biometric clocks).
• Overtime restrictions to prevent abuse.
• Idle time reduction (e.g., Pathao drivers optimizing routes to minimize waiting).

2. Piece Rate and Incentive Systems

• Workers paid per unit produced (e.g., a tailor earning Rs. 50 per shirt).
• Pros:
  • Encourages productivity.
  • Reduces idle time.
• Cons:
  • May lead to quality issues if rushed.
  • Not suitable for all jobs (e.g., managerial roles).

3. Standard Hours and Efficiency Ratings

• Standard time = Time taken by a qualified worker under normal conditions.
• Efficiency ratio = (Actual Output / Standard Output) × 100%

Example: A tailor in a Kathmandu factory is expected to stitch 10 shirts in 8 hours (standard time).

• If he stitches 12 shirts in 8 hours, his efficiency = (12/10) × 100% = 120%.
• If he stitches 8 shirts in 10 hours, his efficiency = (8/10) × 100% = 80%.

4. Labour Turnover Control

• High turnover increases training costs (e.g., a call center losing agents frequently).
• Solutions:
  • Better wages and benefits.
  • Employee engagement programs.

Labour Cost Variances

Variances occur when actual costs differ from budgeted/standard costs.

1. Labour Rate Variance

• Cause: Difference between actual wage rate and standard wage rate.
• Formula: $$\text{Labour Rate Variance}=(\text{Actual Rate}-\text{Standard Rate})\times \text{Actual Hours Worked}$$

Example (Nepali Garment Factory):

• Standard rate: Rs. 200/hour
• Actual rate paid: Rs. 220/hour
• Actual hours worked: 500 hours
• Variance: (220 - 200) × 500 = Rs. 10,000 (Unfavorable)

2. Labour Efficiency Variance

• Cause: Difference between actual hours worked and standard hours allowed.
• Formula: $$\text{Labour Efficiency Variance}=(\text{Actual Hours}-\text{Standard Hours})\times \text{Standard Rate}$$

Example (Same Factory):

• Standard hours for output: 400 hours
• Actual hours worked: 500 hours
• Standard rate: Rs. 200/hour
• Variance: (500 - 400) × 200 = Rs. 20,000 (Unfavorable)

Real-World Applications

1. NTC’s Labour Cost Control

• Uses biometric attendance to track overtime.
• Implements shift rotations to minimize idle time.
• Result: Reduced labour costs by 12% in 2023.

2. Daraz’s Delivery Efficiency

• Piece-rate system for delivery executives (paid per successful delivery).
• Route optimization (using GPS) reduces idle time.
• Impact: Faster deliveries at lower labour costs.

3. Kathmandu Garment Factory (Worked Example)

Scenario: A factory produces 1,000 shirts/month.

• Standard time per shirt: 0.5 hours
• Standard wage rate: Rs. 200/hour
• Actual production: 1,200 shirts
• Actual hours worked: 650 hours
• Actual wage rate: Rs. 210/hour

Calculations:

Analysis:

• Efficiency improved (1,200 shirts > 1,000 shirts), but higher wages and extra hours increased costs.
• Solution: Train workers to work faster without increasing wages.

Exam Tip

• Always show calculations for variances (labour rate and efficiency).
• Relate to real businesses (e.g., NTC, Daraz, garment factories).
• Compare piece-rate vs. time-rate systems in terms of pros and cons.
• Memorize formulas but explain the meaning of variances (favorable/unfavorable).
