What it is Filled

A period of time assigned for work, such as a shift, watch or duty period; used for scheduling work in workplaces that operate in turns.

Why it exists Filled

Let an agent describe work periods and shift patterns, compute durations, and point to working-time rules, without giving legal advice.

Distinguishing features Filled

  • A shift is an assigned period, unlike total working time over a week.
  • Watches are traditional shipboard duty periods, including dogwatches.
  • Night work carries special rules in many jurisdictions.

What robots and AI may and may not do Filled

Must not

  • advise breaking rest rules

Only with a human decision

  • disputes, which go to employers, unions or authorities

May

  • describe shifts and rules in general terms

Moral aspects Filled

  • worker health

Who is affected

  • workers

Owners Filled

Steward

the employer that sets the schedule

Master systems

  • rostering systems

Links to other meta-models Filled

parent

  • oewn-15143170-n - registry parent class

related

  • time interval - time
  • work schedule - roster
  • working time law - rules
  • work time - broader period

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.hours
  • Open English WordNet: oewn-15143042-n

Direct properties not applicable Not applicable

Not applicable

A time period has no physical properties; durations are recorded under times.

Recognition optional Filled

  • Shown on rosters and schedules

Capabilities and actions required Filled

  • describe shift types and patterns
  • compute shift lengths and rest
  • point to working-time rules
  • explain night and on-call work

Hazards and failure modes required Filled

  • Fatigue from long or night shifts
  • Insufficient rest between shifts

Standards and interfaces required Filled

  • EU Working Time Directive 2003/88/EC
  • ILO conventions on hours of work and night work (C171)
  • ILO Maritime Labour Convention for seafarers' hours

Context of use required Filled

  • Organising who works when.
  • day shift
  • evening shift
  • night shift
  • split shift
  • on-call duty
  • watch and dogwatch (maritime)

Sources Filled

  1. Shift work - shifts and duty periods
  2. Directive 2003/88/EC concerning certain aspects of the organisation of working time - Shift-work and night-work definitions; working-time, rest and night-work provisions.
  3. Night Work Convention, 1990 (No. 171) - Correct C171 identifier, issuing body and night-work subject matter.
  4. Maritime Labour Convention, 2006, as amended - Seafarers' hours of work and rest.
  5. Watchkeeping in a Warship c1913 - Shipboard duty periods, middle watch and two-hour dogwatches.
  6. Fatigue and Work - Association of night shifts and extended working hours with fatigue and safety risks.

Open questions

  • The registry sense comes from a lexical source and merges many shift terms; should some be separate?
