Translation:Our jobs are the same, why are our salaries different?
"Our work are" This is probably the worst error I've seen in this course
Agree. Also 'Our work is the same, why aren't our wages? (the same) should have been accepted
Could also accept "Our jobs are the same so why are our salaries not the same" with "so" in place of the comma.
Possible reasons: Different companies, different markets, different levels of seniority, different education, different prior experience, or different performance on the job.
I just got corrected to the very ungrammatical "Our work is the same, why is not our salary the same?"
