Hello - I work part-time on the midnight shift, and recently saw a job posting for another part-time position on the day shift. If I take the day shift job, would I then become full-time (working both shifts), or would one job just replace the other? Sorry, I'm kind of new and this hasn't been explained to me. Also, if it's not possible to work both jobs as a part-timer, then how do I become a combo shifter? I've seen many full-time job postings where I work, but they only seem to be available to full-time employees. Thanks.
