My large company went out and bought 20k company cell phones that employees are now required to carry on their person at all times when in a company building, just like your badge. The phones have both a bluetooth Covid-tracking app, and a 'work pass' app that makes you answer the standard exposure questions every day. You have to show the generated work pass to the security guard when you get your temperature checked as you enter the building. We assume that company legal decided they couldn't mandate the app install on personal cell phones, hence the new ones.
We're on a 50% rotating schedule in the office, and cubicles were moved such that nobody has another person in an adjacent cubicle on their shift.
So far, we've had three reported cases of Covid-19 in my building, of which I had the honor of being first, back in August. Thankfully still around to post this.
As annoying as the phone app and other measures are, I do think the company has done a pretty good job. We are considered an 'essential' business, so completely closing isn't an option, and a good chunk of our R&D simply can't be done at home.
