A typical education consist of a 2-yr technical degree if you want to become a forest technician or a 4-yr degree in forestry from a Society of American Foresters accredited university if you wish to become a forester.
A typical work week varies by sector (e.g., state government, federal government, municipalities, self-employed, not for profit, or private sector).
Furthermore, there are many different fields of forestry: urban forestry, silviculture, hydrology, soils, economics, recreation, fire ecology, pathology, entomology, wildlife, engineering, social/policy, wood products, spatial analysis, biometrics/modeling, and the list goes on. Therefore, the work week varies by discipline and by the agency or company you work for!
So, it really is quite difficult to answer your question since forestry really is a broad discipline. If you have additional questions, please feel free to call me directly and I can provide you with some more details!
Thanks for the question :-)
