Your DMs know nothing. RDs may have vague ideas, but will be/were sworn to secrecy under penalty of job loss. DMs will find out very shortly before the ax falls. If you're in a city and lots of reps are selling identical products, it's likely that you'll get tagged. Look for the tenured, high pensioned to go, but the outside firm that orchestrates this is wise to spread the pain to avoid the obvious legal entanglements.
Start banking some cash to live on. Convert anything liquid to the same. It's all just stuff. Get conservative on the way you live. Get your resume updated. Do a reality check, millions are out of work; many with skills other than buying lunch and leaving samples. Not a put down, but a reality!
