I think everyone got confused by what the OP was asking. I was in a similar situation so I understand. He wants to go AD, but since it takes a long time from the day you fill out the application until the day you actually get paid, he is trying to find out if he could switch to the ANG and possibly take a charter job if his current job comes to an end. It sounds like ideally, he would like to stay at his job now and go AD, but since it can take months to years to go AD, and he is not sure that his job will last that long, he is looking at other options. If he takes the charter job with his friend, he does not want to quit a week after he starts if the AF finally gets back to him. If he could go to the ANG, then he can keep the charter job so he doesn’t screw his friend and serve.

The same thing happened to me. I waited 12 months (6 of them without a phone call/returned phone call from the AF), so I found a 4 month 135 job. On my second day, the AF got back to me and told me my class date was in two weeks. Luckily, my former CFI was able to take my position so the company wasn’t upset (also, the CP is AF and knew they could call at any moment so he was happy for me). Unfortunately, going to the Reserves or ANG means you start all over again, so that is not an option. You could just take a job at Burger King until the AF gets back to you, but I can’t blame you for trying to keep/get a flying job while you wait.
