That's why I liked Google so much: you don't have to "suck up" to anybody. If things aren't working out, figure out what you'd like to do instead and 2 weeks later you're working on that, if they have spots on the team and would like your help. You may be asked to stay a bit longer, say 6 weeks, but the process is very non-confrontational. It's not like that for junior people, though - if you're junior you have to stay in your position for at least a year, which IMO is dumb - people who work there have no problems finding employment elsewhere. It should never be harder to move within the company than _outside_ the company.
Yeah for a big company there is no excuse. Smaller companies might be more impacted by giving people this freedom but maybe the advantages outweigh the disadvantages anyway.
