I got to ask, has reading comprehension really come down that much in the recent decades?
Could the title be expanded to be more prosaic? Sure!
But at the same time, it's intuitively and entirely understandable.
Who? GAME staff
What? Discovered something
What exactly? That they're moving to zero hour contracts
How? Via a mass Microsoft Teams call
Or, written together, the title up above. And that's a completely normal sentence structure, it's essentially how your brain should expect a sentence conveying that information to be structured, or the final part would be at the start ("Via a mass microsoft teams call...").
