I had a job offer and to start the onboarding procedures my employer sent me a soft-copy of the contract by email. I signed it and sent it back by email. The employer also sent me an hard-copy of the contract by normal post. The hard-copy had some other documents I had to fill and send back within a given date. The problem is that I received the hard-copy only 2 days ago and I should have sent everything back yesterday. As I am still working at my current job (notice period) I did not manage to be on time with the delivery.
What to do? Would this negatively affect my future job?
