"This actually happened just a few weeks ago. I was given a timeline for getting some things done and right off the bat, I was thinking it seemed like a really short timeframe. I took some time to map out a plan: if I worked on certain things first, it would make the later tasks a little easier. About one week into the job, I realized I wasn't sure if I was going to be able to get everything done on time because of some parts that were on backorder. I talked to my supervisor frequently to let him know my progress and my concerns, but also assured him that I would do what needed to be done to get it done. I did have to stay late a few times and even asked a coworker to help just a little, but I did end up getting everything done. In the end, my supervisor saw that I worked really hard and understood that maybe the short timeline wasn't as reasonable as he originally thought."
