None...............other than reducing each of your W-4 "allowances" to zero and giving the new W-4 to you employers..and see if that works for next year...then re-adjusting as needed at that time. That will have each of your employers withhold more.
More income means more taxes. Whatever W-2 is entered first...ALL of the deductions, exemptions are applied to whichever one is entered first...then when the second eon goes in, then all of the second income is being taxed instead of only part of it.....that's quite normal.
