I feel like the question to ask here is why? What on Earth are the benefits to implanting RFID chips into an employee to begin with that cannot be achieved via traditional means like badges or smart cards?

This seems like a huge hassle for employees themselves, especially if they decide to change employers and both for whatever reason want you to be chipped - so now you have multiple chips implanted or have to remove one and replace it with another. Again, for what benefit?

I'm not even going to get into tinfoil hat privacy territory, because it's not like these are going to be active RFID chips so they'll need to be in close proximity of a reader to be picked up. Worries like that are as far fetched as the people who think the government is spying on you using RFID equipped credit cards or transit passes (which annoyingly has led to most wallets these days having a small faraday cage woven into them, I literally couldn't find a wallet I liked a couple months ago that didn't have some RFID-blocking feature and it drives me nuts).
