I just joined a MNC 6 months ago to do finance but recently my boss instead gives me a ton of ancillary tasks like video. How should I voice out or quit to find another job because I'm not developing?

Agree with everyone here - as long as the ancillary task is not morally questionable, your job as the newest hire is really to help the team out, not just in the role your were hired for but also for tasks that help the team achieve its larger goals. Just make sure that you document what you have done for your performance review, and then ask if your boss is happy with what you have done. Also continue to perform in your other tasks, and if all goes well, you would have easily demonstrated that you can do your core job + extras = you are ready for the next level. It will then be very easy to request at a later time for larger roles that you prefer + for an intern to do the videos etc. Everyone has to pay their dues in most jobs!

This is the working world nowadays. Employers are facing a cheap labour crunch and so they are extremely reluctant to hire new workers. Instead, they pressure existing workers to take on menial jobs. So we all just have to deal with it. It is very common. As someone here mentioned, actually as long as it is not taking up too much of your time, dont be too troubled by it.

If however, the side tasks are taking up too much of your time and are too menial, find a better job and jump ship. All the talk about self-development and ra ra positivity is not very helpful imo if basically u are just a convenient person to carry out menial and pointless tasks.

Always put yourself first, not the company. No one will do it for you.

I would say yes do it.pick up new skills sets While you are young. The world is changing with technology your new skill sets might open new doors while being A specialist is good you never know when you might be replaced.

if you do it well this might become your bargaining chip to better things in the company.

After a while have a honest chat with your boss on your progression and aspirations. If at end state the answer is still status quo and you are not happy with it then you can decide to move on to a new job

It will be good to be flexible to accept the other work assignment so that your boss will appreciate you better. However, if you are not comfortable, you could perhaps speak to your boss regarding your jobscope. Whatever the case, do be tactfully and do not burn your bridge.
