It's not only Google but Intel, HP, Microsoft, Nike and MANY MORE Corps abuse...I mean use contractors. It's an issue the Federal govt needs to make a decision on imho. Look at the grubhub lawsuit in CA. Corp dont want to bring in full time people because they will have to pay them more, and give them all the benefits/perks etc.
Knowing Intel, they have a resolving door with positions. You can be a contractor for years in the same job and never be a full time employee. I.E A clear sign of misclassification. Intel has been getting away with it for years. They would rather bring in an H1B, or someone that fills a diversity quote than bring in someone local and pay them more. I've seen in over and over and over the last 10 years.
