This is definitely a good point, when everyone is wfh things like slack or (bleh) Teams has everything in it. I am an internet kid and used im to communicate with my friend base for a long time, it works for me and I can stay connected with people that way, it seems like some people aren’t able to utilize that effectively.
I work for a large Corp that has offices in several location, prior to covid wfh, information was often silo’d just to certain locations and there were people on teams I didn’t know because they never post in slack/teams and instead just do everything in person. All of a sudden I’m seeing them post and ask questions/comment when they rarely/never had before.
The company is now instituting RTO and claiming it’s in the name of collaboration and culture, but if anything I think wfh helped a lot to make cross-site collaboration and culture more prevalent.
