As an aside, I really dislike this pattern of deliberately misleading headline. Make it appear that you're asserting a point of fact, Google illegally spied on workers before firing them, knowing that's how the reader will read it, then modify it at the last minute to dial down your commitment to the claim, with US labor board alleges. You'd never use this structure in conversation, you'd just say it the natural way, US labor board alleges Google illegally spied on workers before firing them. Unfortunately even the BBC uses this style sometimes.
