It's not about improving productivity, increasing innovation or 'sharing best practice' (as my former workplace put it.) Corporations are forcing a return to office work in an attempt to curb a post-COVID real estate crash.
For one place where I used to work, RTO drove down staff morale to an all-time low (already low due to high workloads and bad wages) and pushed the staff turnover rate in my department to 95%. They ended up having to outsource the function to an overseas firm.
