Stop with this partial, tapered, odd/even, get your behind back to work at the office! I have never seen more employee whining or coddling by employers in my entire life.
But why, if it doesn't provide measurable benefit to the employer or employee?
It is because that's what you have to do, therefore everyone else must do it?
Some jobs (working in a retail store) are going to require physical presence. Other jobs may have some benefit by means of simplified communication in office spaces, but an awful lot of jobs require a lot of time spent doing some solitary activity that requires no human contact at all - not even via remote conferencing.
The time you spend collaborating in person should be proportional to its increased efficiency, not just unjustified presenteeism.
Remote working is one of the few things in life that can actually be a win-win for employer and employee.
Employers can get work time out of works because there is a tendency to use at least some of the previous commuting time actually working. Employers can have smaller office spaces that don't require a desk for every employee. They save on infrastructure costs for heating, electricity, internet bandwidth, computers etc.
Employees have less stress and a better work-life balance with more flexible working hours, with more sleep and probably more time for exercise, hobbies or social interaction (with people they choose). They save money by not commuting, buying lunches, coffees etc
Office time should be for collaboration, information sharing, customer meetings, social events etc.
