I seriously want to punch this manager in the face.

I've been working at Ulsan Hyundai Heavy Industries for about 10 years.
This manager, the absolute piece of sh*t, comes looking for me every time a problem breaks out.
There are plenty of other people, and many who work better than me,
so why does he only look for me? Because of this manager, I've been on business trips to Mokpo Hyundai Samho Heavy Industries over 30 times,
3 trips to Saudi Arabia, 2 trips to the UAE, and 6 trips to Dubai. F*** this...
I think I've been on business trips to the Middle East more than 20 times.
During personnel transfers, I applied to the cabin production department 6 times,
but I got rejected every single time, and I feel like absolute sh*t.
Honestly, compared to the workload at Hyundai Heavy Industries, the salary is tiny,
and man, I'm so stressed out. The weather is also freaking hot, so
working trapped inside welded steel makes me feel even worse.
Even if I consume more than 5 glucose tablets a day, I still get anemia.
