For now…
" As of August 2023, 12.2% of U.S. workers are fully remote. More than 4.7 million U.S. workers are remote at least half of the time. Only 11.1% of private sector businesses are fully remote. 65% of workers want to be remote all the time, while 32% prefer a hybrid work schedule."
When you subtract out those that do not ever work in an office like an electrical lineman, oil worker, etc. the percentage of office workers drops dramatically by comparison.
