Why sick leave matters

Sick leave is important to employee well-being in Australia. It helps students and employees get the much-needed time off when suffering from an illness. A sick leave certificate online acts as trustworthy proof of absence for employers and institutions. Whether it is a simple flu or an infection such as COVID-19 that needs extended absence, sick leaves help in ensuring you can rest and recover without losing pay. According to the Fair Work Ombudsman¹, full-time and part-time employees get 10 days of paid sick or carer’s leave per year in Australia.

Top reasons Australians take sick leave

Common reasons for sick leave in Australia

Common illnesses:

Most common illnesses, such as cold, flu, fevers, cough, stomach-ache and more, are some of the main reasons for sick leave. Some of the common illnesses for which employees take sick leave include:

• Colds, fevers, and flu
• Stomach-ache, gastro, food poisoning, diarrhoea and vomiting
• Infections such as sore throat, viral illnesses and more

Chronic conditions:

Changes in chronic conditions such as asthma flare-ups, migraines and more might require some time off from work or school to recover, leading to sick leave. If you have some changes in conditions, such as blood pressure, that affect you, you can get a day off as well.

Mental health reasons:

Mental health disorders, including anxiety, stress, and depression, are now widely accepted as valid reasons for taking sick leave. These conditions can significantly affect a person’s ability to focus, communicate with coworkers, and work performance. If you are feeling burned out or stressed due to work, these are also considered as valid medical leave reasons in Australia.

Injuries:

You can take a day off from work or a long leave for injuries in personal life or at work. A sprain, an ankle injury, a back injury, fractures, accidents and physical trauma are some examples of injuries you can take sick leave for.

Pregnancy issues:

During pregnancy, women may require time off for health reasons, including morning sickness, complications, or medical appointments. You can get sick leave for pregnancy issues in Australia.

Carer’s leave:

Whether you need to take a day off to care for your loved one, assist your parent to the hospital or be with your child when sick, it is all accepted.

Musculoskeletal disorders:

Issues such as joint pain, back pain, and injuries due to physical strain are common reasons to take off from work or school.

Why workplaces require a medical certificate?

According to the Fair Work Act 2009, employees are entitled to paid sick leave every calendar year and the employer has the right to ask for proof of this illness. This proof is none other than a medical certificate from a registered practitioner. A medical certificate validates the illness because of which an employee is taking leave. This helps in solving any trust issues that might arise at the workplace or can be used as legal evidence in some cases. This is a formal letter from a qualified doctor or health practitioner in Australia, reaffirming your illness. This ensures a sick leave is only taken when you have a valid reason. It prevents misuse of sick leave, laying unnecessary workload on other colleagues and acts as legal record in cases of disagreement.
