It's my understanding that when it comes to resumes, shorter is better. However, it is also my understanding that the entirety of your work history should be included, as well as of course things like education, references, other relevant skills/certificates/experience.

Unfortunately, due to circumstance and having moved around a lot, my work history is fairly lengthy. Bare bones, short explanations (ex. "Keep building and surrounding grounds clean and clear of trash and litter") it comes in at 2 pages, which is what I have been using. With more detail for each position, it becomes 3-4, but actually tells you what I did as an Usher at a movie theater, or a gardener in a greenhouse.

How do I reconcile this?
