To counter the problem of low employee retention, some fast food companies have come up with the solution of hiring senior citizens, people who typically have a very low attrition rate. However, the time taken by senior citizens to service an order is higher than average. Thus, for most fast food chains the gain in employee retention will not compensate for the increase in fewer customers served on an average and the resultant decrease in profits.
Which of the following, if true, taken together with the information given above supports the assertion that hiring retired people will probably not become an industry-wide feature?
(A) The government has laws under which companies cannot refuse employment to senior citizens purely on the basis of their age.
(B) Surveys indicate that senior citizens are generally more patient while dealing with customers than employees of other age-groups are.
(C) Only the most successful fast-food companies initiated the employment of senior citizens to counter the problem of low employee retention
(D) By law, senior citizens are entitled to the most comprehensive employer sponsored insurance plans.
(E) On average the difference between the time taken by other employees to service an order and that taken by senior citizens is three minutes.
