Read the following case study and answer the questions given in the end.

It gets more than 3,000 applications a day. And it's no wonder!With a massage every other week, onsite laundry, swimmingpool and spa, free delicious all-you-can-eat gourmet meals,what more could an employee want? Sounds like an ideal job,doesn't it? However, at Google, many people are demonstrating bytheir decisions to leave the company that all those perks (and theseare just a few) aren't enough to keep them there.Google has been in the top five list of "best companies to workfor" by Fortune magazine for four years running and was numberone on the list for two of those four years. But make no mistake. Google'sexecutives decided to offer all these fabulous perks for several reasons:to attract the best knowledge workers it can in an intensely competitive,cutthroat market; to help employees work long hours and not have todeal with time-consuming personal chores; to show employees they're valued;and to have employees remain Googlers (the name used for employees) for many years. But a numberof Googlers have jumped ship and given up these fantastic benefits to go out on their own.For instance, Sean Knapp and two colleagues, brothers Bismarck and Belsasar Lepe, came up with an ideaon how to handle Web video. They leftGoogle, or as one person put it, "expelled themselves from paradise tostart their own company." When the threesome left the company, Google really wanted them and their project tostay.Google offered them a "blank check." But the trio realized they would do the hard work and Googlewould own the product. So off they went, for the excitement of a start-up.If this were an isolated occurrence, it would be easy to write off. But it's not. Other talented Google employeeshave done the same thing. In fact, there are so many of them who have left that they've formed an informalalumni club of ex-Googlers turned entrepreneurs

Q2:Despite all the perks being offered to the employees, why are they leaving the job atGoogle? What types of challenges are being faced by managers in keeping their employees motivated?
