Y1 senior is at 4k, give you +- 200.

4.2k x 14 months = 58.8k

Looks like a lot, but you have to divide by 10-12 working hours instead of the usual 8.

Per hour salary is 58.8 / 52 x 5 / 10 hrs = $22/hour.

Others who are paid 4k and 8 working hours are getting $27/hour. These people get 4k straight in year 1 aka fresh grad while you have to wait until year 3 aka Year 1 Senior. The gap only closes after about 5 years but by then it is almost impossible for you to overtake those who have earned extra during their first 4 years.
