Should I Go To Work If I Have A Fever?

When It Makes Sense

• Good fit: You have a low‑grade fever (below 100.4°F/38°C), feel otherwise well, and your role can be performed remotely or with limited face‑to‑face interaction.
• Good fit: Your workplace lacks a formal sick‑leave policy, you are the sole person on a critical, time‑sensitive task, and you can take strict precautions such as wearing a mask, frequent hand hygiene, and keeping distance.

When You Should Avoid It

• Warning sign: Your temperature exceeds the commonly used fever threshold (100.4°F/38°C) or you experience additional symptoms like cough, body aches, or fatigue, indicating a potentially contagious illness.
• Warning sign: Your job involves close contact with vulnerable populations (e.g., healthcare, food service, education) where transmitting infection could cause serious harm.

Pros and Cons

Pros

• Maintaining income and job continuity, especially if you have limited or no paid sick‑leave benefits.
• Preventing disruption of urgent projects, client deadlines, or essential services that rely on your presence.

Cons

• Increased risk of spreading infection to coworkers, customers, or the public, which can lead to broader absenteeism.
• Potential worsening of your own health by not allowing adequate rest and recovery.

Decision Checklist

• Is your temperature below the threshold (100.4°F/38°C) that typically defines a fever?
• Can you fulfill your responsibilities remotely or with minimal physical interaction?
• Have you consulted your supervisor about company sick‑leave policies and communicated your condition?

Alternatives to Consider

If you’re uncertain, consider taking a paid or unpaid sick day, working from home if your employer permits, or delegating critical tasks to a colleague. Many organizations provide flexible arrangements for short‑term illnesses, which protect both your health and workplace continuity.

Final Recommendation

In most cases, staying home when you have a fever—especially if it exceeds 100.4°F or is accompanied by other symptoms—is the safest choice for you and for others. If your fever is low, you feel capable, and you can isolate yourself effectively (e.g., remote work, strict PPE), attending work may be reasonable. Always check your employer’s sick‑leave policy and, when in doubt, consult a healthcare professional.
