Changing job right after starting

[caelite]

Hey guys

Found myself in a bit of a situation I am wondering how I should work it. Basically I've been working in my previous job for a year and a half and for the last 8 months or so I've been pretty desperate to get out (low paid, have a very bad relationship with my immediate superior and was really struggling to drag myself in every day). So last month I had chucked my CV out to a few dozen local places. Got some notice and attended 3 interviews. I was immediately offered a job from 1 of the interviews to start when my notice period was over (14 days), I accepted this position. So I just started and finished my first working week with them however I was just offered a position from the 2nd interview I attended and if I am honest it is a much better position than that I have already accepted (better pay, hours and a company I would actually like to work for). But I really dont know how I can work this without coming over as a complete tosser.

The notice period for my new job is 14 days aswell so in theory I could hand in my notice and tell the 2nd employer when I can finish without telling them I had already started another job. But I think Im going to really come off as a total dick doing this which Id rather not do since the team im now working with seem alright. Both jobs are low level retail so some level of employee throughput are too be expected I suppose (2nd job is retail with technical work & better pay to reflect it, company rhymes with hall frauds).

I know there are a lot of managerial types about here Id love some advice from, would I be coming off as a dick for immediately quiting to accept a slightly higher paying/more fufilling role? Provided Im not using this company for references due to my short time there is there any way it could come back to bite me in the ass in any way other than my morals?

Thanks

Cheers for the advice folks

Yeah I reckon I was being stupid and worrying a lot over nothing. Didnt get a chance to grab my manager today as work was rather hectic (normal for Mondays for building supplies supposedly) but Ive accepted the new job and told them I can start in 14 days starting tomorrow. Sent my manager an email at lunch time explaining my situation and asking if we could have a chat tomorrow at some point regarding it. She's no got back to us but it should be sorted tomorrow regardless as I have given her my 'notice' via email.

Thanks again for putting my mind at rest somewhat
