I work for the federal government so we don't have a lot of details yet but my understanding is we will be allowed to choose, and they expect most people will go with a hybrid of working from home and going into the office once or twice a month for meetings and such, which would need to be booked at "hotelling" desks. This is what I expect, and am very much hoping to stay home. I believe we will be allowed to go clean out our desks at some point this fall, in a controlled manner, most people left everything behind as we were only supposed to be home a few weeks. I am not sure if it will begin this fall though, they have a lot of logistics to work out, and people are reluctant to give up working from home, and also going in when we don't know if everyone is vaccinated or not. I don't think there will be a full time presence in the office until next fall. I am also told we are following federal guidelines rather than provincial, since we have offices across the country and each province has different restrictions.
From talking to my coworkers/friends in the office, most of them don't want to go back. I know one person who misses being in the office and one who misses our coffee breaks
but everyone else is content at home. One lady I work with is very close to retiring and I think if they forced her back she would go early, but she does a lot and we can't afford to have her leave yet.
