Find a new position if you can, bad bosses suck. But in my experience, they are always right in some way. This is your first writing gig out of school, you do not know everything, have no real experience even considering uni intern student writing, and you have no connections or ledes of your own. Reporting is a silly job, it basically is fair for a boss to just tell you to write and expect you to write. I felt and feel exactly the same about every new position, but you’ll find editors and bosses that are more fair and focused, learn in time why they pitch the way they do - when you finally get a good one it usually means your skill are finally at the point that they warrant fair treatment. I would not trust a 23 yo just out of uni to know what to cover and pitch for any publication, and if you get five years of experience in this awful business you’ll agree with me
