Most companies and a large amount of their employees were never able to make the jump to remote work mode. That is, they were trying to recreate the office experience while working remotely. The result of this is employees that are exhausted from being on zoom all day and a complete disappearance of work life balance. Moreover I suspect that the lack of in person meetings has also led to a lot of cases of misalignment and in some cases even conflict between different teams. Management sees this and they also get a lot of requests from employees that want to go back to the office which leads them to the conclusion that remote isn’t the best long term solution.
But like I said, this isn’t the fault of remote work but instead the result of companies not adjusting to a remote work mode.
With the hybrid approach they will get the best of both worlds. People will be able to have “meeting” days and “maker” days, which should lead to an increase in productivity without burning out the employees. At least that is the theory, only time will tell.
