I have already accepted a new job at is initially only for 6 months with a view to going perm that I am due to start in 2 weeks and I have already signed the contract, I have now been offered an other position at a different company and I would like to accept as its a better job in the way of the level that I will be, it's permanent, only 20 miles each way as opposed to 43 miles each way, better prospect and an overall better financial package.. But I am concerned as I have already signed a contract and also that I don't wish to let anyone down.
Please help as need some urgent advice before Monday.
