What do you understand by Line Balancing Explain with an example?

Line balancing is the practice of assigning workloads and monitoring to make sure that everyone is doing the job they need to be doing. An example would be a telemarketing office with several employees. If a person is polishing their nails, for example, instead of answering phones, that person is going to be leaving the company if the other employees are being overworked because of it.
