(1) On graduate school applications that ask for a work history, is it permissible to omit jobs--such as waitressing, temping, working retail--that have nothing to do with the program to which you are applying?
(2) If so, where is the line drawn to make a job something you are truly expected to report on the application? If you babysit now and then, do odd jobs for a day, or "help out" in a store for a few weeks, are admissions committees truly interested in knowing that? More to the point, is it dishonest to leave it out?
For an idea of the specific context, here is text from one graduate school's question about employment history:
"[List] employment experience (including part-time) since secondary school""
I ask about the general case here.
