I will also be released 3B in three years and I'm already looking into the PH and what I should do to make sure I get the kind of job I want post release. In my opinion, the success of the program has a lot to do with planning your release and really knowing what you'd like to do after.
- what kind of education you have will make a big difference in the kind of positions you will be offered. I only have a GED so I'm already looking into completing at least a certificate while I'm still in the CF. That way, I'll only have to complete 2 more certificates during the 2 years of voc rehab to get a bachelor's degree. I can then expect to have better positions offered to me (AS instead of CR) as well as much better salary.
- what trade you're in before you release also makes a big difference. Sadly, a clerk will probably be offered a job much faster than some other trades (infantry for example). Your limitations will also be a factor.
- getting familiar with the PSC website and what kind of tests you may have to do is also something to consider. The kind of jobs you'll be offered are the positions posted on the job.gc.ca website. Personnally, I've been applying for various jobs just to be able to do the tests. I figure that if I pass them, I'll have valid results forever that will help me in the PH process. If my scores aren't high enough, I'll at least know what I'll need to work on in case I have to redo the tests. So far, I did 6 of the most common ones, plus the second language evaluations (which I did a few years ago).
Granted, I'm really lucky to get a full 3 years and most people only get 6 months before their release (9 months for LFQA reservists) but that should be enough time to think about what you want to do after and look at your options. To me, the two things a person needs to avoid when facing a medical release are : 1. do nothing and wait for an amazing job with an insanely high salary to magically fall on your lap, and; 2. be bitter, angry and have a bad attitude about the whole process. You may not like the way the CF treated you, or your CoC, but the 6 or 9 months you get before your release is the perfect time for you te reevaluate your life and the goals you want to accomplish when you'll ne longer be in the CF.
Just my opinion.
