Apple's employees are full of optimism about the company's future, but don't expect to see the results of it in their pay packets, according to research by New York-based research firm Vault.

The research company has published the results of a new employee survey on the hardware giant. Vault claims its employee surveys give investors and jobseekers insight into the company's business operations.

A number of excerpts from the survey are available online, much of which is positive, but there is some criticism. A former customer solutions specialist says: "Just as any large corporation the large scale structure, the organization gets lost at the lower levels. The micromanagement needs to be but to a minimum and something needs to be done to increase retention and lower the turnover rate which is substantial."

Another project manager observes: "This should be a good year for Apple but it will not reflect in my salary or any kind of bonus I dream of receiving."
