I strongly expect to see the lower income unemployment rate drop pretty hard in the nearer future, given that not all states are using the FEMA assistance for their unemployment systems, and even with the number that are, that money will run out and benefits will go back to pre-COVID levels of lower-than-your-original salary. Once that really starts setting in, and with the high job posting rate, employment will jump up.
This ignores the group of people who have pre-existing conditions and really can't go back to work without possibly even excessive social distancing, but I'm unsure the magnitude of impact that will have on the labor force...
...and the group of people who have pre-existing conditions, but can’t afford to miss work, get sick and go bankrupt, become disabled or die.
So "they" seem to have settled on "K" for it.
If I can suggest an alternative, what about "Y-shape" where you tilt your head a little bit so that the bottom of the Y points slightly to the right? (Edit: after googling this it seems I'm not the first to propose this.)
The economic problems started playing out before the shutdowns.
