Modern Moms Guide to Telecommuting by Lauren Stern
Overall good book, it has a good structure and examples. Unlike some of the books this one does not get into statistics (which we can find from other sources). The Kindle version of the book is free.
The book mentions six key attributes for being a successful telecommuter:
a. Disciplined and self-motivated
b. Ability to work with little supervision
d. Flexible and adaptable
e. Ability to stay connected with your co-workers
The book is well-written but not specifically for virtual employees; anyone can use the principles. One comment that stood out was—Approach virtual work by assuming that no one understands what you do.
