I work for a big employer but in my department it's just me and a few others. In the last few months both managers of our department have left and there's not really been an official replacement, just other senior staff come in and help out when needed but they are not my manager.
I need to give my notice in and I have no idea how to do it. I need to give my notice by this evening to ensure I can start my new job on time. I emailed the notice to HR yesterday but they haven't responded to acknowledge their receipt of it. Should I send another email asking if they have received/accepted it or is informing them enough?
I don't know if I should also email some of the senior staff the notice too? The thing is it would result in a disparity between when I gave my notice to HR (yesterday) and when I give my notice in to senior staff (today). I'm working this evening (night shift) so I'm wondering if I should bring a letter printed out to give to whoever is working in my department tonight?
I have never given notice in a job before so not sure what to do.
