One-off changes vs permanent changes

When something about a class needs to change, the first thing InstructorHUB asks is whether the change is for one date or from now on. Getting that distinction right is what keeps pay correct, because a change to a single occurrence and a change to the class going forward have very different consequences. Every change lives behind one Make a change action on the class, so you pick what kind of change and, where it matters, from when.

For a single date, you have a small set of clearly separated actions, and they are separated on purpose because the pay outcome must never be ambiguous. Cancel a date means the class does not run and nobody is paid for it. Mark absence also stops the class running, but the instructor is still paid, which is the right choice when a class is called off but the teacher is covered by their arrangement. Mark as holiday suppresses the class with no pay, tracked separately as a calendar holiday. Each of these touches only the one date you choose, and each can be reversed: a canceled or holiday date can be reinstated, and an absence can be removed, putting the occurrence back to running and paid as normal.

A permanent change is one that carries forward, and those ask you for a date it takes effect from. Move or swap the instructor from a date puts a new person on the class going forward while leaving earlier dates paid to whoever taught them. End the class early sets the last date it runs, so it stops generating classes and pay after that point. Because both apply from a date rather than to a single occurrence, they reshape the class from then on without rewriting the past.

The practical rule is simple. If a teacher is away next Tuesday, that is a one-off: mark the absence or arrange a cover for that date. If a teacher is leaving the class for good, or the class is finishing for the term, that is permanent: swap the instructor or end the class from the right date. When the change is really about who teaches one date rather than whether it runs, a cover is usually what you want, covered in Cover and substitutes.
