Is 3,542 the film work force? Or everyone they have?

As terrible as layoffs are, 30 of 3,542 isn't too unexpected for a large company. I expect their yearly turnover is much higher from regular departures. If everyone stuck with their jobs for 15 years before changing position that would still be an average ~236 departures and hires annually.

Just saying, not much we can get without context here though Photo Engineer may have a better sense of how they operate.
