First, I wouldn't make assumptions for the hiring manager, in regards to your consideration of a bachelors degree. Sure, there may be a few individuals who would not hire you if they felt your education plans might interfere with work. Nonetheless, I bet most will be open to the idea, provided you can provide a fairly high level of assurance that you have a plan in place to handle both work and school
Second, finishing your degree is a great idea. If you're 33 now, do you really think it will get easier to finish a degree when you're 35? 40? 45? Probably not. While I wouldn't recommend going through an online 'degree factory' program, there are definitely programs out there designed to accommodate working individuals.
Hell, if you need to retake the basic education courses (ie, the first two years of a standard four year program), most community colleges offer night/online courses that are dirt cheap and will probably fit your schedule. After completing an associates, you would only need to finish two years of schooling from an accredited university. The greatest benefit here is that you would only have to pay for two years of 'real college' but you get to take advantage of a real alumni network, real recruiting events, and have better 'degree-brand-recognition' than anyone who went through an online school like Phoenix.
In short, don't let the fear of losing a job stop you from completing your education. Just be ready to explain how you plan on structuring your work/school schedule, so as to provide assurance that you will be a reliable hire.
