Left US in just one week time.

I am in a possession of valid H1B visa for Employer A. Due to some employment conflicts and family emergency I have to leave US within just one week of joining ( I did not resign ).

  1. Will this impact If some other employer want me to work with him in future ( till my H1B does not expires ) ?

  2. What if Employer A changes his mind and asks me to start working with him again.
