Homeworking seems as though it will be here to stay, at least in some sort of blended form, for the foreseeable future.
I have been conducting many homeworker assessments (via zoom) over the last few weeks, as well on line workshops, and the consensus seems to be a September return to the office, at the earliest. There is a very real concern of the safety of offices at the moment, although some are desperate to leave their homes and get back to a semblance of normality. This is especially true where employees have limited space or lack of privacy.
The IES survey conducted research in to how homeworking was impacting employees and found that, on average, 50% reported an increase in aches and pains. This has been clearly reflected in my assessments.
