Answer:
-2.3%
Explanation:
Labor productivity basically measures how much output does each unit of labor generates.
total labor used during April = (6 employees x 40 hours) + (4 employees x 25 hours) = 340 labor hours. Labor productivity in April = total output / total labor hours = $60,000 / 340 labor hours = $176.47 per labor hour
total labor used during May = (6 employees x 40 hours) + (2 employees x 25 hours) = 290 labor hours. Labor productivity in May = total output / total labor hours = $50,000 / 290 labor hours = $172.41 per labor hour
the percentage change in labor productivity = ($172.41 - $176.47) / $176.47 = -2.3%
