There are many things. For example, having a rude boss who constantly criticizes you for no good reason. One of my friends had a boss like that. He would nitpick at every little thing she did, and it made her dread going to work every day. It really made her days at work terrible.
I had a terrible day at work last week. I woke up late and rushed to the office. As soon as I got there, my boss scolded me for being late. Then, I found out that I had made a big mistake in an important report. I had to spend the whole day correcting it. And on top of that, the coffee machine was broken, so I couldn't have my favorite coffee to keep me going. It was really a nightmare of a day.
Sure. One day at work, I woke up late and rushed to the office. When I got there, I realized I had left an important report at home. Then, during a meeting, I made a huge mistake in presenting the data. My boss was really angry and scolded me in front of everyone. It was so embarrassing and made the whole day feel like a disaster.
Maybe you get stuck in traffic on the way to work and are late. Then you find out you've missed an important email. During the day, you could accidentally break some office equipment.
Sure. I got to work late because my alarm didn't go off. Then I spilled coffee on my important papers right before a big meeting. During the meeting, I couldn't find the report I was supposed to present and made a fool of myself in front of the boss. It was just one disaster after another.
Sure. In a short story of a terrible day at work, one common experience could be getting a huge amount of unexpected tasks. For example, I once came to work and was suddenly given a pile of paperwork that needed to be done by the end of the day. Another is dealing with difficult co - workers. I had a co - worker who was always negative and it really brought down the mood in the office. Also, technical problems can make a day bad. Like when the network goes down and you can't access important files.
One common element is unexpected bad events. For example, like getting a flat tire on your way to an important place. Another is a series of misfortunes. Maybe you spill something on your clothes and then miss the bus right after. Also, things not going as planned, such as a party being cancelled last - minute due to unforeseen circumstances.
Well, here is a story. I planned a lovely picnic with my friends. But in the morning, it started to rain heavily. All the food I prepared got wet. And then I realized I left my phone at home so I couldn't call my friends to cancel. I just sat there in the rain, feeling so miserable. That was such a terrible day.
Maybe things like losing something valuable. For example, you could lose your favorite watch. Or getting into an argument with a good friend over something silly. That would make the day feel terrible.
