It’s human nature to take credit for work thats not ours and just go with the flow, especially in the working environment. A boss gives you credit for a job that your colleague did most of the work on, what do you do?

I would notice his gratitude but at the end of the day, or maybe the same hour, i would have a talk to my boss and let him know that i didnt deserve as much credit as he gave me. I would tell him that my colleague did most of the work and he deserve most of the credit because am sure he would feel bad (my colleague) and he might not want to work together on any other given assignments in the future.

By takig credit for his work might also ruin our working relationship. it might create a hostile environment for us to work in. So i would do the the right thing and take the fall, if i slacked off, why should i get credit? It would be morally right for me to tell my boss that my colleague did most of the work and i don’t deserve as much credit.
