Thanks Brandie. I've been working with SQL for about 3.5 years now, so as a general statement it would seem like you're saying "no, it's possibly not worth it".

I am, however, thinking more on changing job rather than job security (I'm pretty sure no one from my company read this post) . I'll probably see 2017 out with my current employer and then move on. I'm not sure I can really improve my skills much further where I am, or at least not practically (ideas I bring to the table are often resisted as too many concerns that it'll "break" something, and the promised test/dev server is still yet to arrive over a year on), so looking at expanding that other ways, and then going somewhere where I can make use of them and learn the practicality of them.
