1. Mark who is really unavailable
Start with today’s facts, not the full company list. Record the absent actor aliases and note anyone leaving early or arriving late. Use aliases rather than contact details, especially for students.
2. Remove scenes that cannot run
A scene is blocked when even one required performer is missing, unless your production already has an approved understudy or stand-in process. Do not quietly change the staging assumptions just to make the schedule look full.
3. Find work with no cast collision
If two rooms or leaders are available, pair scenes only when the cast lists do not overlap. A single shared actor makes simultaneous rehearsal impossible, even when both scenes are otherwise available.
4. Keep a useful fallback menu
When no complete scene can run, choose bounded work that does not pretend the missing actor is present. Examples include:
- line accuracy for the actors in the room;
- movement, transitions or prop hand-offs that exclude the absent role;
- music, dialect or text work already planned for that group;
- notes review and a short problem list for the next full call.
Safety, supervision, room availability and production policy still outrank schedule efficiency.
5. Record the decision, then re-plan
Write down what changed, what was completed and which blocked scene needs priority next time. A short record prevents the same absence from creating invisible gaps later in the process.
