Annoying coworker

[HazelSnail]

I know I'm not bu. Or maybe I am!
A new coworker has just joined the team, she's from a completely different industry and just doesn't have the knowledge of our industry which is absolutely not a problem but she's come in thinking she's the queen and acting like I should be grateful for her, very often wrong, opinions. I'm not grateful I actually find her very annoying and borderline rude when she suggests changes for my work (we do not do the same job). I can't tell her to keep her nose out and I can't complain to management as she's so new I don't want to put her off!! I'm just finding her exhausting to deal with currently as I'm rushing around trying to do my work but she complains all day about how she's so tired and struggling with everything and often leaves an hour early leaving me to pick up her work too! Any tips for how I can suck it up and deal with it?

Do not pick up her work. She will just have to do it when she comes in the following morning. If she is finding it too much suggest she goes to management and asks for a comprehensive induction program and extra help.

Why do you have to pick up her work? If she is leaving early this needs mentioning to her manager.

If you do different jobs how do you pick her work? It sounds like a very small team if that's the case, so it could be awkward to bring anything like that up.

You can refuse to do her work and just leave it til the next day so that she can pick it up. Then you aren't taking up someone else's slack and if there's a problem leave her to work it out with management.

Very small team sorry i have been deliberately vague. Say I manage day to day operations and she deals with enquiries and such. So I can ignore her work but then it impacts me when it's not done and there's such a team spirit attitude that I'm sure I'd look petty

There's no team spirit attitude here, Op, just one worker palming her work off onto another.
