I have considered adding the physics; but I'm a little rusty. I use math up to and including calculus on a regular basis, I haven't touched physics since college. I'm guessing I would be ok with a little brushing up though.
And call me an eternal optimist, but I just don't think the current status in teaching can stay this way. Eventually retiring teachers need replacing and expanding classes call for more teachers. So while it may not be ideal to make the leap right now, I'm sure the pendulum will swing the other way at some point.
I will warn you that this will sound like I am a Debbie Downer...I was at our union meeting this afternoon. Please know that I LOVE being a teacher. I have been teaching for fifteen years.
Eventually - could be a long time. Our district (PA) is offering early retirement package for the second year. Other local schools are considering the same. They will NOT hire to replace. This is a way to cut money and save current jobs.
Another teacher here. Have you thought at all about teaching Tech Ed classes? I'm a HS teacher and I teach CAD, Drafting, Engineering, Architecture and Interior Design.
Many of the teachers in this field are old and retiring
In PA - the budget proposals are beyond frightening. These programs can and will be cut/ reduced in some districts.
While this is a difficult time for anyone to consider a career change (to any career, not just education), I don't think the situation is as dire as some are indicating.
Yes, you will be a newbie to the teaching field, but as such, you'll have some really great attributes working in your favor at this time.
1) You are able to teach math (and physics). It is incredibly difficult to find qualified, certified teachers for these subject areas. Math and science seem to always be in need of good teachers. So, while it might still be a struggle for you to find a job, I think it will be easier than if you were going for a job in teaching any of the other core subject areas.
2) You have little experience. Despite budget cutbacks, schools still need teachers to teach classes. If a district is hiring, you will be the cheaper option, and thus be more appealing budgetwise than someone with many years of experience.
Good luck in whatever you decide to do!
In PA - dire is not a strong enough word. Unions are meeting across the state to address how to do "our part." Corbett called for us to take salary freezes...and yes, unions are voting on this and having it approved. This is to save jobs. Highly likely, that the most recent hires will still be without jobs, so they will have a year or two experience, but still be cost effective for anyone hiring.
Districts are increasing class size in order to reduce staff - heck, furloughs are being proposed, so when teachers are hired, it will be the teachers who were furloughed.
As a teacher who LOVES the job itself, I would encourage you to RUN, not walk away from this profession. It is getting ugly and only going to get worse. I honestly love the job itself, but I would NEVER choose to go into it now, knowing what I know now.
As for alternate route, I don't think you have much of a chance of landing a job that way. There are not any shortages of teachers right now. The only alternate route teacher I ever met was a Spanish teacher. Our district was in a bind and needed someone quick, she lasted one year until our district found a certified teacher and replaced her.
I don't know if I would tell you to run- walk briskly maybe...

I do love what I do, but I am worried about job security. Again, I have been teaching for 15 years. If House 558 passes and there is an option of furloughs not based on seniority...I am paid twice what new teachers are. I am a dedicated teacher with a reputation to match, but I am feeling more vunerable to losing my job. With my current adminstration, I feel safe. However, what happens when my administration changes? Also, with the attack on unions, I am worried about not having protection against an angry parent (for every 250 supportive ones, I do encounter one irrational one).
The district I teach in has to find 11 million dollars if Corbett's budget passes.
I really do hope that this turns around, but I don't anticipate it to be better for another 3 to 5 years if we are lucky. Politicians in PA are very interested in funding vouchers for school choice which only hurts public school education.
I am being practical. Teaching in PA is not a promising option. The field is flooded with candidates. That said...you might be lucky, so I wish you the best. If finances aren't a concern, go for it.
