No matter how great a company is or how many perks they offer, sometimes you just know when it's time to move on, even if it's a multinational Internet and software corporation such as Google.

Business Insider shares a couple of reasons on why some employees decided it was time to pack up and move on. You might even be inspired by these stories to rethink your job options:
  • If you aren't an engineer, get ready to be below everyone else. At most companies, it's the product manager that's more valuable than the engineer. At Google, engineers get the final say in just about everything. That leaves designers, ad operatives and just about everyone else in the dust. Several former Google employees we spoke to said this was the case.
  • Sometimes, it's time to move on. Two former Google employees we spoke with said they had been at Google for an extended period of time and wanted to try something new. A lot of them move onto new companies.
  • If you're at a satellite office, you might feel disconnected. The former Google Wave team left because they felt like they weren't getting their say. One former Googler said that New York wasn't really a satellite office, but just about everything else was. You have to make your presence felt in Mountain View if you want to have a say in the company.
  • Some go for the bigger, better offers. Facebook is the largest company where former Google employees end up. Seriously — who wouldn't want Facebook, Google and Microsoft all on their resume? One former Googler we spoke with said this was a huge draw.
  • Some are feeling the entrepreneurial itch. Chris Dixon tweeted just a short while ago some Google diaspora: Ev Williams, who founded Twitter; Kevin Systrom, who founded Instagram; Dennis Crowley, who founded Foursquare; and Ben Silbermann, who founded Pinterest. One former Googler we spoke to did just that, and got a nice acquisition deal out of it.
