My company is giving a half day for each shot, so no thanks J&J
(not to mention my appt being on the day of the J&J shutdown). Took under an hour with commute and got 4 hours off for it.
ETA: Just anecdotally, for those in Queens, the York College site is great. There's a free parking lot, the site is quick and efficient (FEMA/national guard run), and they're currently doing Pfizer.
