Not every job looks the same. A business choosing how to structure a role is a bit like choosing the right container for a liquid — pick the wrong shape and it either overflows (staff burn out, costs spiral) or there's wasted space (staff sit idle, money wasted on hours nobody needed). Let's go through the main "shapes" a job can take.

This is the "standard" job — an employee works the total number of hours the company defines as full-time in a week, typically 35+ hours. Full-time workers are usually the backbone of a business: they get the most training investment, the most benefits, and the most job security, but they also cost the business the most per employee in wages and benefits combined.

Someone working part-time might only do two or three days a week. It's more flexible for both sides — an employee might want fewer hours because of family, study, or another job; an employer might only need someone for part of the week (e.g. a shop that's busiest on weekends). Costco in the US, for example, requires part-time staff to work a minimum of 24 hours just to keep their employee benefits — a reminder that "part-time" doesn't mean "no strings attached" for either side.

Imagine one full-time role, sliced like a pizza, and split between two (or more) people, each working part-time. A classic example is a split-shift job share: Worker A covers 8am–1pm, Worker B covers 1pm–6pm — together they cover the same working day a single full-time employee would, but as two separate contracts.

These workers show up only when the business actually needs them — this could be seasonal (a ski instructor working two months during the winter season in the French Alps) or for a fixed, determined length of time. It's the business equivalent of renting rather than buying: perfect for short bursts of demand without long-term commitment.
