The problem with "using your network" for an older worker, is that in a severely ageist climate, your network has to be made up of those who are 10-20 years younger than you are. These kinds of connections across generations are difficult to forge in a way Dan Lyons illustrates better than I can. I have found that "network" as a resource is better explained as "knowing someone with CEO hiring power and strong desire to hire you in particular." If you are in your early to mid 40s, you may have built strong connections of this type, but many of those who are in powerful hiring positions don't want others around who can compete at their level, because they face the same thing comming for them. And many more who have this power these days are much younger than they used to be, which makes them less likely to hire someone they see as "mentor age". It feels awkward and unnatural--they want to hire those they can come up with, just like in any other time in history. I feel that this "get a job through your network" advice tends to become very thin at around age 35 and up, especially if you are a member of another protected class.
