Lesson 07 published. Map, example, EX061.

flowchart TD
  M["The group check asks: who is a member today?"] --> P["Last month one former staff member was removed"]
  P --> T{"Is a later leaver still in the group?"}
  T -->|Yes| F["That person is this month's finding"]
  T -->|No| K["Cite today's list, not last month's sentence"]

A past removal proves last month. Membership is read again.

Logical drawing

monthly check: only current staff in the paid group
first month: one former member removed, dated
a later person finishes
    |
    +-- last month's sentence does not name this person
    +-- "we already cleaned the group" is not a new look
    +-- the person stays a finding until removal is dated

Learning outcomes

After this chapter, you should be able to:

  1. Treat the monthly membership check as a look at the current group.
  2. Refuse to close the check by citing one earlier removal.
  3. Record a later leaver as open until the removal itself is dated.

7.1 The question is who is in the group now

The first month's notebook records one former staff member taken out of the paid messaging group. That line is evidence about that person and that date. The check Kwame set is narrower and repeats: are the people in the group current staff? A classmate says the group can be skipped this month because it was cleaned once. Skipping would miss anyone who left after that date. Kwame opens the member list. If a person whose last day has passed is still there, the finding is an open membership, and the removal is written with the date. He does not add a personal name that the case file does not contain.

Reason to skip the check What the notebook holds Decision
"We removed someone last month." One dated removal Look again
"The paid app is a business version, so leavers expire." No such expiry is recorded Do not assume it
A named current employee They still work They may stay
A leaver still listed, no removal date The check's question Remove and date it

Synthetic case. The later leaver is unnamed. Do not invent a name.

Errors and limits

Removing a member does not delete their old rota, and it does not decide the employment keeping period. That period is still the accountant's sentence, which Chapter 11 keeps blank until it is written.

Worked answers

EX061. The later person is still a member. Remove them and date the removal. Last month's removal does not cover this person.
