Peter had applied for a teaching position at a school, and he agreed to start his employment on 25-April-2016. But Peter did not go to the school on the day as promised, he came to the school three days later without any good reasons and so was fired from the job.
Given that situation, I am trying describe it in a simple way,
Peter was fired from his job because he could not come to work on time on 25-April-2015.
But I am not sure whether using "on time" in the sentence can fully describe what happened, or it is incorrectly used. Will people think think he got fired because he was late to work when seeing "on time" in the sentence.
