To answer a question: "When are faculty obliged to be 'on campus'" a.k.a. "what does '10-month' mean?"
For 10-month faculty, generally their responsibilities are considered to start one week before the first day of classes and run through two days after the final exams and grades are due.
If a 10-month faculty member has family or sick leave, it begins August 1st, unless they can document that they did work during the beginning of August.
When can a new 10-month faculty member begin?
New faculty members may be set up with an employee ID and UITS accounts once a Hire Employee eDoc is processed. This can be done before the "effective date". That is, the Hire Employee eDoc can say the hire is effective August 1st, but be completed in May. A Hire Employee eDoc requires a background check and I-9 processing. A new faculty member can live in IU systems as soon as those are completed.
In practice:
Most faculty enjoy significant flexibility in terms of personal, illness, or work-related travel time, during the 10-month appointment. Most units, in order to not disrupt teaching and other schedules, schedule unit-level activities in August before classes, and in May after classes. Flexibility on both sides is usually best for a unit to accomplish its goals.
Background (Source: IUPUI Faculty Guide):
"10-Month Appointments
Faculty members who hold 10-month appointments may engage in compensated activities without accountability to the university during the two months they are not engaged in university business. Moreover, faculty should not be expected to participate in university activities when they are uncompensated but must act in accordance with university employee regulations."
"Summer Teaching Faculty members who teach during the summer are required to be actively engaged in course-related teaching activities from the first day of classes through the day grades are due."
IU policy language applies specifically to prorating of pay, not on work day obligations:
"Those appointed for an academic year are paid on the basis of ten equal payroll checks (five for each semester). It is sometimes necessary to prorate pay because of resignation, termination, illness, or death. The calculation will be based on the number of calendar days falling within a semester. The relevant item is the ratio of calendar days prior to the cessation of work to the total in the semester. This policy is followed for determination of the precise span of time during which the mutual obligations of an employer/employee relationship exist for the purpose of proration of pay, when such proration is necessary, and for fringe benefit entitlements.
Appointments for the academic year and for the first semester begin seven days prior to the first day of classes on each campus. Appointments for the second semester begin seven days before the first day of classes at the campus but never earlier than January 1. Appointments for the first semester terminate on December 31. Appointments for the academic year terminate on the day of commencement for the campus.
Appointments for various summer sessions begin on the first day of classes and terminate on the last day on which final grades are due on each campus."
This is sometimes interpreted to indicate "workday" obligations, but the context is about payments and proration.
Summer Resignations and Retirements:
If a 10-month faculty member resigns or retires after May 30th: during the summer months they have an active AC1 appointment, and summer pay is added to that. That active appointment ends upon the last class day. They do not receive any regular/non-summer pay for August. Regular pay for August is only for 10-month faculty working during that academic year.
