I'm a brand new nurse, who only started working without a preceptor about a month ago. I was called for an overtime/extra shift on my last day off, after only having 2 days off. I know new nurses should take extra shifts more, and I feel really guilty about saying no, but I would be working for 5 days straight for 12 hours each day, and I feel like it would've been too much. It was my first time getting asked to work an extra shift, should've I said yes, especially being new? Or should I not feel bad about not taking the extra work, knowing my schedule and few days off?
