Without a long history at the company, it may be hard for some to feel nostalgic about staying during difficult times. According to a document filed with the Securities and Exchange Commission, Zynga said 80 percent of the staff has been there less than two years. In fact, many employees have joined the company through a dozen or more acquisitions. This short tenure could potentially represent an ongoing challenge for Zynga to manage, as it tries to figure out how to create a sense of dedication among its employees.

Otherwise, Zynga can be like many other Silicon Valley companies offering free lunch and other perks. But now, some employees think it might be the time to pull out the checkbook and spend some of the $1 billion it raised in its IPO on retention bonuses.
