This is true. I work for a unicorn and we've committed to paying all of our contract staff until the office reopens. This includes making special payments to the caterer, even though we've cancelled regular lunch and dinner meal service, just to pass through to their employees so that they can shelter in place and not have to be at risk of either getting sick or not being employed.

It also includes all reception and building security staff, even though they are employees of the building management, and not employed by us.

I hope more people know that SV startups, and especially unicorns, are really leading by example in their treatment of the low-wage service workers and contractors that work in their offices.
