Tiktok no, but FB and Twitter, yes. I work for a law firm that frequently has to access both of them for actual business needs, like contacting another company or joining a group that does communicate between multiple firms for litigation. It isn't the most ideal, but some small companies cannot afford larger programs to host chat/video meetings and do not have the IT staff in place to recommend better alternatives that are free.

Also, I'm IT within that firm and one thing that fails to be mentioned is how strict and monitored that stuff actually is these days. Lot of people will make comments about how "well my IT let's us do whatever we want". Sure. But that doesn't mean we don't know about it and we definitely wink wink, nudge nudge aren't capturing that traffic.
