Although you may be working in an office, it is highly likely that any job functions associated with industries undergoing such shifts will be affected, even within the office environment. It wouldn't be surprising if businesses implemented company-wide changes, particularly in departments dealing with construction or building, regardless of whether an individual's job function is directly related to those areas. Some companies might see this as a cost-cutting measure, such as reducing prolonged use of air conditioning.

Personally, I would be deeply disappointed if this were to become the norm. However, it is unlikely to happen unless one is closely connected to industries undergoing these shifts. I must admit, as someone who is not a morning person, I am not looking forward to such changes myself!

(Also, article does point out potential effect on people working in AC-ed building, too.)
