I was about to suggest bring it up to your supervisor, but then you mentioned that you’re in the Middle East. There may be some cultural norms there that make doing what you’d normally do in the US different.
Since you’re in the Middle East, I wonder if workplace hierarchy and indirect communication styles might be more prevalent. If going directly to the manager isn’t an option, you could try finding a mentor-like figure in the workplace or framing your request in a way that highlights your eagerness rather than frustration.
You might try these things:
Since there was initial confusion about the role, you might want to have a direct conversation with your manager (if culturally appropriate) or another supervisor to confirm your responsibilities. You can frame it as a desire to be effective: “I want to make sure I’m meeting expectations. Could we review my key tasks so I can focus on the right priorities?”Something like that. Or, Something like: “I really appreciate the opportunity here. I want to make sure I’m learning correctly—do you have any recommendations for additional training materials or time with someone who can walk me through the process?” This way, you aren’t accusing the trainer of not doing their job but are proactively seeking a solution.
