the ‘return to office’ lies
Many employees are frustrated with the push to return to the office, which is often justified by false claims about improved collaboration and social interaction. This is especially harmful to those with disabilities or chronic illnesses who benefit significantly from remote work. Office presence is often unnecessary for data-centric roles where most tasks are already digitized. The insistence on in-person work appears to be more about justifying office spaces and micromanagement rather than actual productivity gains. Remote work can reduce stress, prevent burnout, and allow better accommodation for personal and family needs.
