I'd usually say you're already in one situation and the other would be uncertain but it appears that this current job is also uncertain, for, as you said, quite a few things changed recently- first the shift then the hours, and after your probationary period there's still no guarantees.

An extra $370 a week is nothing to sneeze at, but of course, you'd have to weigh the costs to go further, not just on the vehicle but to you.

I wish you the best of luck though, and for what it's worth: great writing, great content, and I'd love to read more from you.
