pink_is_underrated's journey

I recently started my first job as an art teacher at a brand new school in my country, which is still under construction. I was excited to focus solely on teaching art, as I had prepared a full curriculum and study methods. However, during a meeting with the other teachers, I was unexpectedly assigned additional roles. They asked me to also teach IT, despite my lack of experience in computing, simply because I know how to use software like Corel Draw and Photoshop. On top of that, I was appointed to handle media duties and assist with administrative work because of my skills with Photoshop. This means I now have four roles to juggle, while most of my colleagues have only three. I’m feeling overwhelmed and confused, as this was not what I signed up for. Additionally, the salary is incredibly low—less than $23 a month, which is just enough for transport and not a real salary. I was hoping to have time for self-improvement and possibly freelance work, but with all these new responsibilities, I’m worried I won’t have any time left for myself. Is this kind of situation normal in the workplace? I’m really struggling to understand the norms since this is my first job.
