The lecture discusses the bad effects of the four-day work policy, which differs from the main idea in the reading passage that offering employees the option of working a four-day workweek for four-fifths of their normal pay would benefit the whole economy as well as the individual companies and the employees. The professor casts doubts on the reading by using a number of points.
Contrary to the belief in the reading passage that the shortened workweek would increase company profits, the professor says that companies will in fact spend a lot more. First of all, if companies employ new staff to ensure the same amount of work, they will spend more money on training and medical welfare. As well, more office basis and computers are needed.
As a result of the former reason, there will no additional work opportunities because the company will enlarge the workload instead of employing more workers. This is totally opposite to the reading that the policy would reduce unemployment rate.
The lecture also refutes the fact in the reading that the option will be better for individual employees. The professor says that there is the risk of reducing the quality of live because they may be unfamiliar with the job after long relax. In which case, these employees might probably be the first to lose job.
