The current DOL Q and A has had a number of additions and revisions.
DOL needs to mark revisions to current Q/A so that those of us who have been reading this info are clearly cued in that there has been a change in the guidance.
All that is needed is a tag like this: "Revised on March 30, 2020" Or, "Added on March 28, 2020"
As forms are updated - the website should clearly identify that a revised or new version of a form has been published. For example - the original version of the sick leave poster had some problems, and was replaced. But I don't think there was any actual notice that the poster was revised.
