I'm a lurker and not much of a contributor, but I want to address this:
I am a low level federal seasonal employee who is currently in the middle of trying to initiate winter field work. The threat of a shutdown is absolutely creating problems. We are trying to hire workers who have no idea if they will actually have a job to go to in January, people who have been hired and are in a bunkhouse (are they going to be kicked out/lights turned off?), private vendors and small local businesses that we are trying to contract with don't know if they should proceed with agreed upon work, we lose out official means of communications. These are just a few examples.
The shutdown ultimately costs more money than actually funding the work being done. Employees will likely get back pay, but money is lost on unfilled and cancelled contracts, engagements and reservations. The rapport that many of us try to build with the local businesses is can also be squandered.
The shutdown will hurt those involved in this winter's field season.
Thank you for bringing up a very valid point. People forget there are humans involved in Big Government.
