I disagree.
Working alongside colleagues is massively beneficial for the vast majority of new employees, especially young ones. Senior employees should be accessible and visible, and work as role models for such staff.
And the social side of professions can be equally important, especially for young employees moving into new areas.
I know dh's firm provides new employees and trainees with ample social events, for those who want it. As well as promoting young professional groups in the area. This is in addition to providing guidance, work shadowing, being available for a quick question, etc, Being a visible, accessible role model for new staff, especially young ones, is see, as an important skill set and is encouraged by partners.
Whilst they have some flexible working conditions, most of the employees chose to return to the workplace full time, and none choosing to work from home permanently.
