VA Part-Time Vs. Full-Time RN

  1. I haven't been told by HR yet what the main difference is between being a part-time employee versus a full-time employee. I was hired for part-time instead of full-time (I was told it was no longer an available option), but haven't had the opportunity to speak to HR. So I have 3 main questions:
    1) Can part-time workers go over 24 hours a week?
    2) Is there holiday pay on top of shift differentials?
    3) Is 401K, pensions, and health insurance only available for full-time employees?

    Thank you in advance! I figured while I'm waiting to get my start date, I might as well try and get some of my questions answered.
