I work in a secondary school,when I got there initially the proprietress told me they have a salary structure and he present it to me,because of that there was no further bargain and I resumed work.After a year of working,she employed a new teacher in my field to relieve me of my stress of teaching the whole junior arms of the school.To my dismay,the new teacher is being paid higher than my salary and we have same qualification. The new teacher is taking 3 arms now while I have been taking 5 arms before her arrival,but now I still take 3arms like her.please I need advice on how to approach my boss on this issue because am not that good in discussion. I feel used and cheated
