text: i have been at my present job for 9 yrs. on a resume how many past employers do i need to list?   i agree as well.  you should list all of them.  employers want to understand your progression.  if those job are irrelevant to what you are applying for then just put the dates, job title or function, and city, state.  that should be enough to erase any initial doubts about what you did in life before that.  but be prepared to answer any questions about those roles and if they have any bearing on your abilities as an employee or how they shaped you as a person.
