A recent study found that employees at tech firms who take at least three weeks of vacation per year are 25 percent more productive than those who take less than one week. Based on this correlation, a corporate consultant recommends that firms mandate a minimum of three weeks of vacation to boost overall company output.
Which of the following would be most useful to know in order to evaluate the consultant's recommendation?
- The percentage of employees in non-tech industries who take more than three weeks of vacation annually.
- The average number of hours worked per week by employees who take less than one week of vacation.
- Whether the cost of hiring temporary staff to cover for vacationing employees is less than the projected gain from increased productivity.
- Whether the most productive employees are the ones who are already most likely to feel they can afford to take more vacation time.
- Whether employees who take three weeks of vacation prefer to take it all at once or in smaller increments throughout the year.
