ITA with Chuck. It wouold serve them right to have you cut back your hours. Then to make up the diff in pay, you could sign up for OT...when it is convenient for YOU! Unfortunately, this option may mean a reduction in the tuition assist you get, or may affect your health bennies. Since my husband carries the bennies, this is how I would fix them, but that is not of course an option for everyone. Can you change to 12-hour shifts? It is grossly unfair to have you have to make-up time on your weekends off.
When my kids were small, and I was PT, I worked q Friday and Saturday night. FT'ers B**ched b/c I didn't have to do sat and sun like them. Hey, I didn't have to work q weekend either, so if I had stopped, and only done my every other as required, they would have to do more weekends. So, when the sup got tired of hearing them c/o and told me I'd have to work q sat and sunday, I transferred out. Then they got stuck doing more Fridays too, which is not great for singles. So, it works both ways as far as catering to PTer's. Maybe you should approach a few of the PTer's to see if they will make a deal w you. I know it was just convenient for me to work weekends, but hubby had to be at work 7am on Monday am, so I just could not do Sunday nights. This whole aggravation actually gave me a lock of gray hair. I had asked the FTer's, so let me get this straight, you would rather lose a IABP and peds cert nurse, and have to train someone entirely new, instead of letting me work q fri and sat? Yes they said, so I said, See ya! When they called me to moonlight, I said no, I gave all my time to the MICU, who was more than happy to have me q fri and sat night!
My point is, working FT and going to school is hard enough, you need to find a work environment that will support you, they are out there, not try to sabatage you and punish you for trying to better yourself. Look elsewhere, see about a transfer. Screw 'em!
