Staff Work Roster or Shift Schedule

Populated staff work rosters and shift schedules (duty rosters, on-call rosters, nursing and custodial post rosters, control room shift patterns), detected from the roster's own structure: repeated shift time ranges, a day or date column header over rows of shift codes (D, N, E, L, AM, PM, RDO, OFF, OT, OC, AL, on call, leave), and site or role context. Staff names are NOT required, because a roster with names removed still shows when a site is staffed or thinly staffed and where a particular line or post will be.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Medium: the roster structures (runs of shift codes under a day/date header, repeated time ranges) are distinctive, and timetable, TV guide and opening-hours text is excluded. Some operational schedules that are not rosters, such as maintenance windows, clinic session lists or rail crew documents that mention a timetable, will be misclassified in both directions. Time-range matching is limited to quarter-hour values in the colon-free form so that year ranges such as 2023-2024 do not count. The 85/75 tiers are heuristic evidence tiers, not measured accuracy; tests are synthetic rosters.

Known false positives

Enterprise agreement and award clauses, shift-work policies and fatigue guidance that discuss rosters and shift times. Mitigation: Enforce tiers need 8 time ranges or a day/date header over a run of shift codes; clause text has neither. Shift-penalty wording is excluded.
Public transport timetables, TV and radio guides, and opening or trading hours with many time ranges. Mitigation: Timetable, departs/arrives, TV/program guide, episode and opening/trading/business hours wording is excluded from every enforce tier. Rail crew rosters that mention a timetable are therefore missed; accept or tune locally.
Blank roster templates and roster software screenshots. Mitigation: Blank grids have no shift-code run; template/fixture words are excluded through the shared template-exclusion dictionary.
Grade tables or checklists with long runs of single letters (A A A A A A) under a day or date header. Mitigation: Still requires the roster phrase within 300 characters; 85 additionally needs time ranges and site/role context.
