In some countries, employees are generally given two weeks of paid vacation time each year. In other countries, employees are given four or six weeks of paid vacation time. Considering the needs of both employee and employer, what do you think is a reasonable amount of paid vacation time for employers to have?. Give reasons for your answer and include any relevant examples from your own knowlege or experience.
Workers have generally two weeks of paid vacation per year in some countries. In other countries, they get four or six weeks of remunerated leave time. It is my belief that companies must give at least six weeks of paid vacation to reward the effort made throughout the year. Companies need to understand that two weeks are not enough for rest and spending time with family and friends. Employees are more efficient when they have a fair quantity of free time, so they have to perform their duties consecuently with the vacation time given.
