Counter-datapoint: My employer (SAP) has had one case of COVID-19 among their German workforce. The entire office building has been closed down for disinfection and the employees there are asked to work from home for the quarantine period. All other employees (worldwide afaik) can work from home without informing their manager beforehand (as is the usual policy). All non-essential business travel is prohibited, with exceptions requiring high-tier management approval. Only two examples for exceptions were given: travelling to a data center to access physical hardware, and travelling to a customer site to access intranet services.

EDIT: I realize that this response is easier to do for SAP than for the average company since we are all working in front of computers anyway the entire time, with only 1-2% of tasks tied to physical objects (paper forms, server hardware etc.).
