As a content writer, you might have faced these issues:
If you're a freelancer, clients not paying on time (and trying to negotiate your fee)
Clients or your company not adding your name to your published pieces (which makes it hard to provide samples)
Clients or your company not offering in-depth feedback (which makes it hard to improve and grow as a writer)
Clients or your company not sharing the results of your work (knowing how much traffic and customers your content brings in helps you learn about strategy, which helps improve your writing and showcase your work)
