How to Treat Your Colleagues: Office Treat Etiquette & Chat Invites

Milestones to celebrate, food calculation formulas (pizza, pies, desserts), remote team tips, and ready-to-use chat invitations.

Published:

In workplace culture, celebrating personal and professional milestones with food—colloquially known as "treating the team"—is a cherished bonding ritual. Whether it is your birthday, a newborn baby, a promotion, or your last day before a new job, doing it gracefully avoids stress and awkwardness.

Short answer: The most popular and budget-friendly office treat is savory pies or pizza paired with tea and dessert. Calculate 1 large pizza per 2–3 people (or 1 pie per 3–4 people), always provide at least one vegetarian/meat-free option, and post a cheerful invite in the department chat 30–60 minutes before serving.

Frequently Asked Questions

Are you strictly required to treat your team on personal milestones?

No, there is no formal obligation. However, bringing food or organizing a casual snack is a well-established corporate tradition of mutual respect, especially when colleagues pooled money for a gift. If your budget is tight, quality cookies, artisan chocolates, or a fresh fruit basket are perfectly acceptable.

How much pizza or pie should you order for the office?

Standard office catering benchmark: 1 large pizza (12-inch) per 2–3 people, or 1 savory pie per 3–4 people. For a 10-person department, 4 diverse pizzas (including at least one vegetarian option) and a dessert cake or pastry box work best.

How to treat colleagues if the team works remotely?

Host a casual virtual celebratory hangout, send food delivery vouchers (e.g. coffee or meal delivery codes), or order a shared delivery to co-working hubs where local teammates gather.
