Question for people who have developed a video game or studied on the subject.

In the corporate world, how do gaming companies in general (please don't cite specific companies or names) keep the creative talent on payroll? Are they contracted for a specific period of time or are they hired to work under conditions? Is it like a 40-hour workweek or is it akin to setting your own hours as long as the building is open? I'm just wondering. There is no denying Bioware has very little of the experienced, old timers to help keep continuity.
