How to Decide If You Should Call in Sick (2024)

If I Have a Cold or Runny Nose?

If you have other symptoms of a cold or the flu and your nose is running so that you need to blow or wipe it frequently, you are contagious. The nasal secretions will contain the virus, and it will be difficult to prevent spreading it in your work environment.

The CDC advises staying home from work or school while you have symptoms of a cold, such as a runny nose.

However, many people have a runny nose (rhinorrhea) due to allergies. If you have a runny nose, nasal congestion, and sneezing due to allergies, you are not contagious and don't need to stay home to protect others. Evaluate whether you feel well enough to be productive at work before calling in sick.

If I Have a Fever?

If you have a fever, you are very likely to have a contagious illness. If your temperature is anything higher than 100 degrees F, you shouldn’t go to work and expose everyone else to your illness.

The Centers for Disease Control and Prevention (CDC) recommends staying home for at least 24 hours after a fever this high is gone. You will know it is truly gone when you take your temperature and get a lower reading after having discontinued fever-reducing medicines such as aspirin, Tylenol (acetaminophen), or Advil or Motrin (ibuprofen).

If I Have Flu-Like or COVID-19 Symptoms?

The CDC also recommends staying home if you have other symptoms that point towards influenza or if you have a confirmed case of the flu.

While most people with influenza have a fever, some do not. The other symptoms include:

• Chills
• Cough
• Sore throat
• Runny nose
• Muscle or body aches
• Headache
• Fatigue

If you have household members or coworkers who have confirmed cases of the flu and you are feeling these symptoms, it is quite likely they are due to influenza.

The flu is highly contagious and can have dangerous complications for vulnerable populations such as babies, older adults, and those with cancer or other conditions that weaken the immune system. Staying home will help protect these people, especially if your job brings you into contact with the public or you take public transportation to work.

If I Have Stomach Issues (Vomiting or Diarrhea)?

Vomiting and diarrhea can be signs of contagious illness or may simply be too disruptive to get any useful work done. You might have stomach flu such as that caused by the highly-contagious norovirus. Or, it might be due to non-contagious illness such as food poisoning, pregnancy morning sickness, a medication side effect, a hangover, or a chronic condition like inflammatory bowel disease.

Whether contagious or not, either of these symptoms will make you less present at work and put you at risk of complications such as dehydration. It is best to stay home until you are clear of nausea and vomiting and your stools have firmed up.

If I Have a Cough?

If you have a cold or the flu and have moist and frequent coughing, you are still contagious and the cough will spread the virus to those around you. In this case, it is best to stay home until the cough calms down or does not bring up phlegm. Frequent, deep coughing is disruptive to the work environment.

If I Have a Sore Throat?

A sore throat is often a sign of contagious illness, including colds, strep throat, and influenza. In these cases, you should stay home from work.

However, if you often experience a sore throat due to allergies, acid reflux, or dry air, or if you overused your voice the prior day, there is no need to call in sick. One caveat: If you need to talk as part of your job and the sore throat has made it difficult to do so, you may want to take a day and rest.

If I Have a Headache or Migraine?

A headache may be a symptom of influenza or another contagious illness that warrants staying home from work, but there are many non-contagious causes as well.

A nagging or severe headache can keep you from effectively doing your job and it can be a good reason to call in sick. Evaluate how likely it is to affect your performance at work to make the decision as to whether or not to call in sick.

If I Have a Rash?

If you have a rash accompanied by a fever or your medical provider has diagnosed your rash as contagious, you should stay home.

There are many non-contagious causes of rashes, and even though you can't spread it to others, you might be miserable from the symptoms (especially itchiness). It's also possible that your appearance might cause alarm if you deal with the public. In these cases, you will need to make a personal call as to what you are able to manage.

If I Have Pink Eye?

Pink eye (conjunctivitis) is caused by a viral or bacterial infection. Pink eye is contagious. According to the CDC, it can spread in three ways:

• Close personal contact, such as touching or shaking hands
• The air by coughing or sneezing
• Touching a contaminated object or surface then touching your eyes before washing your hands

Many schools do not let children return to school until 24 hours after the child has started antibiotic eye drops for their pink eye.

The CDC states that if you have conjunctivitis, but you do not have other symptoms like coughing or sneezing, then it may be fine to go to work with your healthcare provider's approval.

Importantly, if you do need to attend work with conjunctivitis, take great care to regularly wash your hands and avoid close contact with others.

If I Am Exhausted?

Extreme fatigue can be a sign of a contagious illness, such as influenza. It can also accompany chronic disease, cancer, cancer treatment, heart disease, mental health conditions, sleep disorders, or pregnancy.

Exhaustion can make you unproductive at work and might lead to errors that can be critical in some occupations, either to the job itself or your and your team's safety. You will have to determine whether it warrants calling in sick.
