All employees at Amazon's headquarters in Seattle and Arlington will be expected to work 5 days a week in the office, according to reports.

Amazon's HQ2 Community Day is back on the calendar. Three months after an excessive heat watch postponed festivities indefinitely, the event is now scheduled for Saturday, Sept. 21 -- promising a variety of activities for adults and kids alike.

For all of Amazon’s clout, its plans likely won’t motivate many other businesses to follow with their own five-day in-person workweek, according to some workplace experts.
