I have recently joined a company in a senior position which is offering me a lower salary compared to my junior colleague. Junior in the sense, she has less experience (1-2yrs) compared to me having 4 yrs experience in the same industry. The salary offered for both of us is below market standards. I feel this is a huge insult to my experience and time spent in learning the skills. Also, I didn't have bargaining power or didn't negotiate my offer better as I got laid off due to Covid and was desperately looking for a job for 6 months. What should I do? Should I discuss this issue with my manager/HR and ask for a raise? Should I seek new job opportunities?
