You're absolutely right. As you read in the article, I think telework will become much more widespread in Canada and elsewhere.
The experience brought about by necessity proved that telework is a very interesting solution for people who had not thought about it. I am thinking in particular of people who previously had to travel to other cities for their jobs and who saw that they could have a much shorter work day if they stayed at home.
Obviously, people with children are going to need a lot of support during this transition, when they are forced to telework and cannot come to their offices.
The disadvantage of telework is that it can mask some of the inequities in the employee's living conditions at home that would otherwise be levelled out and go unnoticed in the office. I think we need to keep that in mind.
That said, employers today can offer reasonable accommodation to people facing certain constraints. Usually these limitations are physical, such as a person who has to use a wheelchair and has difficulty getting to the office. Allowing telework as a reasonable accommodation for people with physical limitations could be a positive development as it would provide opportunities for more people.
