Is it appropriate to indicate on one's resumé or CV (next to each employment on a plain reverse-chronological one) why the employment ended? Or is that a detail better left to a face-to-face or phone conversation?
For example, this might be to indicate that one's employment ended because the company closed up shop completely. The question of why a job ended seems rather common, and this might be a way to pre-empt that and provide a brief explanation (which could then be expanded upon in a conversation if the need arises).
I am mostly interested in cases where the employments were reasonably lengthy; specifically, several years long. Also, let's assume that all employments ended on good terms; obviously one that didn't would not be one you want to list, and leaving one out can invite questions (so then just edit them all out).
Also, in a listing of commisions of trust (serving on non-profit organization boards, for example), is it appropriate to list something similar? For example, "departed at own request at the general assembly meeting year X". (Let's not turn that into a discussion of whether or not such a section is appropriate; personally, I feel it helps to show the applicant as more well-rounded than simply a workaholic, and it is easy to edit out of the master resumé before sending to a specific company should there be a reason to.)
