Bank I quit working for 6 months ago did this. During the pandoodle our team was allowed to build itself as though WFH was permanent. Then someone in c-suite realized that the bank owned all the parking garages next to the offices they had all over the country, and that they were missing out on about $12/employee/day, so they started pressuring us to come in. Trouble is, some of our team was in Pittsburgh, some in Cleveland, some in Dallas, some in LA, and at least one we couldn't prove but strongly suspected had his US work permission but was actually working from his family farm in Mexico. So we went from being comfortable in our homes with no commute and doing all of our meetings via teleconferencing to being uncomfortable, having anywhere from a 30 to 90 minute commute depending on which team member you talk to, and still only being able to meet online.
