Konica Minolta are heartless and cruel to their employees

My wife works for Konica Minolta in Centurion two days ago she tested positive for COVID19 due to stress of retrenchment and testing positive for COVID19 she collapsed and was hospitalised and definitely she contracted it at work since the no one from the company ever tried to call and check about her health/well-being only what I received from her emails was retrenchment forms which she has to fill and return them before a certain date. What kind of people who does this they do not care of the well being of their employees so disappointed concerned Husband
