A Reassessment on Remote Working

IBM was one of the original promoters of work from home arrangements for its employees. Given the choice between coming into the office or working at home or remotely, as many as 40% of IBM's employees elected to stay out of the workplace.
I have never been a fan of work from home arrangements for the simple reason that accountability and productivity almost always suffer under the circumstances. Moreover, the benefits of collaborative effort, which include increased creativity, better employee morale, and a more efficient productive process, always seem to suffer when one or more of the participants is not physically present.  Any number of companies have the same experience, and work from home policies fostered a growth industry in disability act complaints and accommodation requests.
This phase of relaxed worker management may be coming to an end. IBM has given its workforce a choice of either resigning or showing up at work.  The company cites the need for better group efforts and faster paced productivity.
Is this a trend?  I don't know, but given the millennial workforce's focus on being part of a team for all but the most basic aspects of work, it would seem that promoting collaborative effort through physical presence is the wave of the future.
