Eh, generally the chips considered here aren't even remotely near high level tracking mechanisms, nor will they be any time soon. They're mostly just fancy security cards at this point, except you don't have to dig it out of your pocket or whatev' when it's time to go through a check. Roughly the same shit we put in chip enabled credit cards and junk.
We have a lot of the tech needed for a subdermal chip able to track basically everything, up to and including geolocation and health readings and shopping habits and whatnot, but that shit is hella' more expensive than anyone is going to spend to keep track of some schlep down in marketing. Or at least anyone sane and/or intending to stay in business, because doing so would be a notable competitive disadvantage vis a vis employee costs and mean your less stupid fellow companies will pull ahead of you, bit by bit.
It's possible that'll change at some point in the future, but that point in the future is pretty solidly guaranteed to not come until someone figures out a way to make high function subdermal chips and their installation and maintenance cheaper than the same thing except not stuck in fleshy bits.
... won't lie, I'd rather imagine what's going to happen faster is an app (template) of some sort that does all of the stuff HR/upper admin/marketing wants done, except the employee shoulders the cost of installation (i.e. buys and keeps running an applicable smart phone) if they want to get and stay hired.
