Any junior doctor / medical student that leads a project in my group/ writes it = first author. Any junior doctor that contributes to a Projects but doesn't lead it = authorship. Don't work with anyone who doesn't offer this.
Don't accept anything else- irrespective of what people may tell you. If you don't value yourself / efforts no one else will.
When involving more junior colleagues in projects you are supervising, it's key to be transparent with them
1. They will be accredited for their hard work. In what formats.
2. ☝️
Please don't take advantage of more junior colleagues as someone to do your projects for you.
