Fall 2020 is the first year that the new universal part-time faculty salary schedule has been used. It is directly tied to the full-time faculty schedule with every cell exactly 85% of what a full-time faculty member with those credentials and experience would earn for 1.0 Lecture Hour Equivalent (LHE). The other 15% of a full-time faculty member's salary is for other departmental and college related duties beyond either their classes or non-instructional assignments.
If you have only had non-instructional assignments for the past three years, and only have a non-instructional assignment now, we can easily work out how your new pay relates to your old pay. You can see here a mapping grid from the old hourly pay rates to the new Salary Schedule B-1. So if your pay rate in Spring 2020 was $74.88 = Group 3, Step 2 (top table), you will be placed on the new Salary Schedule B-1 at Group 6, Step 8 (bottom table).
It doesn't matter what your specific assignment is, once you know the total LHE of your assignment for the semester, you simply multiply the amount in your cell on Schedule B-1 by that LHE and then you know what your total pay will be for the semester.
On Salary Schedule B-1, Group 6, Step 8 has a cell amount of $2,704 which is the pay per semester for 1 LHE. If you have an assignment of 9.0 LHE for the semester, you simply calculate 9.0 * $2,704 = $24,366 for your total pay for the semester.
The UNITS listed on a pay stub do not represent hours worked, but are the number of weeks in the pay cycle times the LHE of the assignment, as long as the assignment is for 18 weeks. The first two pays of a semester (Fall: September, October; Spring: March, April) are for 4 weeks of pay, and the last two pays (Fall: November, December; Spring: May, June) are for 5 weeks of pay. Again, note that if your assignments are not spread over 18 weeks, the UNITS will be split out differently over the semester, but your total pay for the assignment is still just determined by the total LHE of the assignment.
The weekly assigned hours of any semester-long assignment multiplied by the load factor of that assignment gives you the LHE of the assignment. All non-instructional assignments are load factor 0.50, so this means that an assignment of two non-instructional hours per week for a full semester is equal to one LHE. For example, 18 hours of counseling per week for a full semester is equal to an assignment of 9.0 LHE, or 10 hours of reference desk work per week for a semester is an assignment of 5.0 LHE.
If you have a counseling assignment of 12 hours per week for a full semester (= 6.0 LHE), and are in Group 6, Step 8 (cell =$2,704), you will be paid 6.0 * $2,704 = $16,224 for your total semester's assignment. Your pay stub will show a RATE that is equal to the amount in your cell ($2,704) divided by 18 weeks = $150.22, which is really the weekly pay per LHE, and therefore your pay per hour of counseling is half of that amount, $75.11 (slightly more than your hourly rate of $74.88 in Spring).
If you have a counseling assignment of 18 hours per week for a full semester (= 9.0 LHE), and are in Group 4, Step 9 (cell = $2,589) you will be paid 9.0 * $2,589 = $23,301 for your total semester's assignment. Your pay stub will show a RATE that is equal to the amount in your cell ($2,589) divided by 18 weeks = $143.83, which is really the weekly pay per LHE, and therefore your pay per hour of counseling is half of that amount, $71.92 (slightly more than your hourly rate of $71.52 in Spring).
If you had a mixture of teaching and non-teaching assignments in the last few years, your placement may be slightly different to this purely non-teaching example due to the previous differences in rates for different kinds of assignments.
