Answer:
B
Explanation:
The supervisor lacks supervisory skills.
Tasks such as this should be performed by a team of people. Each person should be assigned different tasks. From the above analysis, it clearly shows that the supervisor wants the workers to offload packages from a truck before moving to the next one.
The best he could have done is assign each workers task based on their area of expertise. While two workers are offloading directly from the truck, they pass the package to another who in turn passes to the next available person till the package reach its destination.
This would have saved more time and stress-free. Once they finish with a truck , they then go the next one till all trucks are unloaded.
