Ebook: Crisp: Your First Thirty Days, Revised Edition: Building a Professional Image in a New Job (Fifty-Minute Series.)

I made this assigned reading for new employees. It covers topics (in a slim 77 pages) that many new workers just don't know, such as appropriate attire, being on time, etc.
"Your First Thirty Days" gives tips on building co-worker relationships, coping with skill deficiencies and improving work habits.
