Employers & Coronavirus

Apologies if this topic has been posted previously. I work in an office of about 10 people, with sales people & drivers occasionally in the office. Two people who are in the office daily felt ill, one about ten days ago & another about a week ago. We were advised that they have both been tested for Coronavirus. One of these people has advised a co-worker that their test as not processed because they didn’t meet testing criteria at the time. That person continued to say that their doctor advised that they could now be re-tested, but they’re so far along with the illness, they should just “ride it out”. Meanwhile, the employee who’s been out for about a week has apparently not received or is not sharing test results with co-workers.
I’d have to believe that the status of both employees has been communicated by them to management. Yet we’ve not been advised of anything, and, in fact, have been told that, unless we’re feeling ill, we must come into the office.
Our office is a bullpen style, open room with fully visible desks & office equipment shared by everyone in the office.
Not trying to sound like a conspiracy nut, but I’m feeling that the management is waiting until someone else in the office is symptomatic to allow remote working, which is very easy in our business. In the meantime, nobody knows if or whom may have been exposed, because we don’t know if our co-workers on self-quarantine have tested positive.
We had begun alternating days in the office with days working from home, but senior management decreed that people who aren’t determined to be ill must be in the office.
I personally believe that this is being mishandled, and that we’re not being provided full information regarding the status of our I’ll co-workers. We had one message sent out to us regarding the potentially infected co-worker who’s been out the longest time, and nothing further since. This seems very irresponsible to me.
What do you think?
