That the world of work has changed is more than clear, but some managers are reluctant to stop visually "controlling" how their collaborators work. They are the ones who are most resistant to working online in their companies.
A summary of an internal Microsoft study ( WTI Pulse Report ) on how its people work has been published, and for this they have interviewed 20,000 employees in 11 different countries.
And I think the conclusions can be extrapolated to most companies. It is clear that work has become a hybrid, spending some days in the office and others at home, and that is not going to change in the future.
Bosses would like to have more people for more time in the offices to "see and control" how they work, and they use meetings excessively, both in number and duration.
In virtual meetings, when they are not very operational, people get bored and carry out other collateral activities such as sending emails, chatting, etc…

In the end, this change affects us all and managers must get used to monitoring their collaborators based on the results achieved, and measure the feedback with the appropriate tools, of which there are many besides the telephone.
Work is no longer just done in a physical space, but must be an experience that unites people in offices and at home. Being aware that the physical proximity of an office favors the formation of teams and work with common objectives.
People like the social and personal relations of the offices, and what will have to be done is to make good use of the time, so that the employees want to go to them some days of the week. Work is no longer sitting in a chair pretending to work.
In the end, all this can result in benefits for companies and workers. Everyone gains flexibility and companies save good money on travel and hotel expenses, which can lead to better financial results.
