Following the increase of sick leave entitlements in 2021, there has been a recent surge in sick leave and absenteeism in New Zealand. These absences are leading to loss in productivity and decrease in morale for many workplaces, making employers question the integrity of some absences. How do you ensure that your employees feel trusted while making sure no one takes advantage of the sick leave entitlements?

In our best practice guide for employers, we explain the basics of sick leave, necessity of medical certificates, and ways Peninsula can help your business. Please note that the below information is general in nature.

Medical certificates and medical opinions

It is a delicate balance for employers protect the health and safety of their employees whilst also balancing the needs of the business. This can be difficult with high absenteeism and employees on long periods of sick leave.

Employees are entitled to 10 days of sick leave upon six months of continuous employment with the business. Although the odd day here and there to recover from an illness is common, employers may start raising questions if patterns begin to develop.

Requests for medical certificates can be a useful strategy to gain evidence of sickness and ensure it is being used for genuine sickness. Additionally medical certificates will also help an employer meet their health and safety obligations as they can ascertain the employee’s current capabilities and potential length of absence.

Depending on the severity of the illness, injury or the impact to the business, a medical certificate from a general practitioner may not be enough to make an informed decision about the employee’s capabilities and potential to return to work. An employer can look to request a medical opinion from the employee’s specialist doctor or other health professionals to make conclusions about the employee’s fitness for work.

Who pays for the medical certificate?

The cost of getting a medical certificate or medical reports depends on the length of sick leave and when the request is made. When an employer requests an employee to show proof of their illness, the following rules apply:

  • Less than three days of absence: the employer must pay for the cost of the medical certificate.
  • Three or more consecutive days of absence: the employee must pay for the cost of the medical certificate.

Acceptable proof of illness or injury

A medical certificate will outline if the employee is sick or injured and cannot work, and when they are expected to be fit to return. If the employee is caring for a spouse, partner or dependant; the employee must retrieve a medical certificate to confirm their condition. It is an employer’s duty to keep these medical certificates for record keeping purposes.

An employee may also provide a statutory declaration as proof of their sickness, although this is uncommon.

If an employer asks for proof of sickness or injury, and the employee does not provide this, the employer may withhold sick leave payments.

Health and safety audits

If there is good reason to believe the illness or injury of an employee occurred in the workplace, a further investigation may be needed to identify the cause. These investigations are usually handled by a dedicated WorkSafe New Zealand doctor.

The purpose of these investigations is to find out:

  • If an employee has been, or is being exposed to, a hazard.
  • The overall level of exposure.
  • How much the employee’s health or wellbeing is or has been affected by the exposure.

If the investigation proves that the illness or injury came from the workplace, the employer will need to cooperate with WorkSafe to make sure the incident does not happen again, and penalties may apply depending on the situation.

Manual Handling

If you are a small business owner or employer, your employees may be involved in some manual tasks at work. These could include picking up things or detailed actions including physical effort. By definition, manual handling is the act of pushing, pulling, or using other bodily force to lift and carry loads. Many businesses require their workers to perform some manual handling. Whether it’s retail workers stacking shelves or factory workers assembling products on conveyor belts. Any task, if performed poorly, incorrectly, or for too long – can pose a risk of injury. The most common types of injury are lower back pains, neck pain, and problems with shoulders and arms – including forearm, elbow, wrist, hand, and fingers. These injuries can result from lifting a heavy or unbalanced load only once, or from continually lifting a heavy or unbalanced load. Sometimes these injuries lead to permanent disability and expensive compensation claims. You can reduce disruption to your business by reviewing the tasks your employees do manually and working out how to avoid injuries. Examples of manual handling Regardless of what industry you are involved in, many businesses require their workers to do manual handling tasks that are potentially harmful. Even remaining stationary for long periods can result in short or long-term injury. Some examples of manual handling tasks include: Pushing and pulling trolleys Operating machinery Packing boxes Lifting heavy equipment or objects Leaning over to scan grocery items or wash dishes. Types of manual handling injuries Understanding the type of manual handling required in the workplace, and the effect it has on the human body can go a long way to preventing injury. Musculoskeletal disorders (MSD) are the most common type of injury and disease that occurs due to manual handling. These injuries affect the musculoskeletal system (i.e. bones of the skeleton, ligaments, joints, and cartilage) and restrict movement of the human body. Depending on the activity that leads to the injury, MSD can occur in the form of: Sprains, strains, and direct blows to muscles, ligaments, and tendons. Back injuries include damage to the muscles, spinal discs, nerves, joints, and bones. Injuries to joints and bones, along with injuries to the shoulder, neck, arms, elbows, legs, knees, wrist, hip, hands and feet. Soft tissue injuries (e.g. hernias). Chronic pain that lasts for three months or longer. Acute pain that lasts for less than three months. Muscular and vascular disorders as a result of hand or arm vibration. Some manual tasks may also be hazardous or dangerous. Hazardous manual tasks are tasks that require a person to lift, lower, push, pull, carry or otherwise move, hold or restrain any person, animal or thing that involves one or more of the following: Repetitive or sustained force. Repetitive movement. High or sudden force. Sustained or awkward postures. Exposure to vibration. Hazards can come from work tasks and how they’re performed or poor work design and management. They can also be the result of physical work environments or the way tools, equipment and objects are handled. Steps to reduce manual handling injuries – training and risk assessment Teaching your employees how to correctly perform manual tasks is an effective way to prevent injuries and avoid expensive claims. Many private training organisations offer face-to-face training at your chosen location and convenient online courses to suit your needs. By professionally training your workers on proper manual handling techniques, they will learn how to: Identify the risks and hazards of manual handling. Be familiar with workplace safety requirements and obligations. Correctly use mechanical aids. Adopt the correct lifting techniques. Handle different manual handling scenarios related to their role or position In some cases, you may not need formal training to identify and manage a risk. Introducing mechanical aids or making small changes to work processes or procedures can go a long way to minimising risks. The weight of the load is critical but also important is the frequency of lifting, posture while lifting, the surrounding environment, and the employee’s physical fitness. When you assess any manual handling, always consider the task, individual, load, and environment. You should also have manual handling posters around the workplace to inform employees how to perform certain tasks correctly. Make sure your employees always follow the operating instructions and limitations set by the manufacturer of any products or equipment they are handling. You can eliminate risks of manual tasks or manual handling with good work design. For example, automating any task or systems to eliminate the need for workers to carry loads. Workers compensation Employees who become sick or injured due to work are, in most circumstances, entitled to compensation. Employers must help sick and injured employees gain access to the advice, guidance, and financial support they need to recover and, where possible, return to work safely. Compensation claim payouts are given to employees in one of three ways: Directly from the insurer to the employee. From the insurer through to you. Through an approved workers’ compensation regulator. Each state and territory has its regulations when it comes to workers’ compensation. Therefore, how and where you go to submit a worker’s compensation claim and the amount of money the employee can expect to receive, will depend on the relevant state and territory.

Lone Working

The way we work is changing rapidly. Companies and businesses are evolving, and employees can now choose different ways of working, such as hybrid work, remote work or lone working. Lone working has traditionally always existed but with businesses turning global with a local twist, there’s a need to revaluate lone working. In this guide for employers, we explain lone working, who is considered a lone worker, the risks involved with lone working, and your responsibilities as an employer. Please note that the information below is general and not intended to act as advice. If you need health and safety guidance, consult a professional. Lone working Lone working is when someone is working by themselves and/or work in the community with limited support arrangements, therefore exposing them to risks by being isolated. Whether they work alone regularly or only occasionally alone and do not have access to immediate support from managers or colleagues, they are considered lone workers. If an employee cannot be heard or seen by their colleagues or supervisor, they are considered to be working alone. Examples of lone working Remote, isolated, or lone workers include: All-night convenience store and service station attendants. Sales representatives, including real estate agents. Long-distance freight transport drivers. Agricultural workers, scientists, park rangers and others doing field work alone. Health and community workers working with members of the public but isolated from their colleagues. Emergency services. Horticultural workers. Parking attendants. Some lone workers are at a fixed workplace but isolated, or in a maintenance role that takes them all over the worksite. “On call workers” who work overtime, outside normal hours or who open and close work premises, can also be lone workers. Lone working legislation If you are a person conducting a business or undertaking (PCBU), you must manage health and safety risks to your workers, so far as is reasonably practicable. This includes when they are working remotely or in isolation. The model WHS Regulations (regulation 48) specifically addresses remote and isolated work. This includes the requirement for PCBUs to: Manage the health and safety risks to remote and isolated workers. Have systems in place to effectively communicate with workers. As a PCBU, you must, so far as is reasonably practicable: Provide and maintain a work environment that is without risk to health and safety. Provide adequate and accessible facilities for the welfare of the workers. Monitor workers’ health and safety and workplace conditions to prevent work-related illness and injury. Give workers the necessary information, instruction, training, and supervision to do their job without risks to health and safety. Consult with workers, health and safety representatives (HSRs) if you have them, about health and safety issues that may directly affect them. Lone workers’ WHS duties Workers including employees, contractors, subcontractors, labour hire employees, outworkers, apprentices or volunteers have a duty to: Take reasonable care for their own health and safety while at work. Take reasonable care to not affect others’ health and safety. Comply with reasonable instructions. Cooperate with reasonable policies and procedures. Hazards of lone working Lone working, remote or isolated work can involve both physical and psychosocial hazards with the risks exacerbated by poor access to emergency assistance. Remote or isolated workers may also be seen as ‘easy targets’ for violence. Lone workers are at higher risk than others because of the nature and location of their work. They risk violent attack, whether from a thief when opening or closing work premises, or because they work in an area of social deprivation or with vulnerable people. Some lone workers risk being in serious road accidents or injuring themselves because of previously unknown poor health. Other implications for lone workers include: Unfamiliarity with the risks of a remote worksite. The possibility of adopting unsafe practices because they have no supervision. Manually handle tools and equipment between vehicle and workplace or during deliveries Fatigue. Cannot get help or advice in case of sudden illness, accident or another emergency. Managing the risks of lone working The risk management process involves identifying hazards, assessing the associated risks, implementing the control measures to eliminate or minimise risks, and regularly reviewing control measures to ensure they remain effective. As a business owner, you have to be proactive in identifying risks associated with lone working as it may take longer to implement safeguards in those locations. The first step in identifying hazards is to undertake a risk assessment. When looking at risks of lone working, consider: How long the person might work alone for. The time of day when a person may be working alone. What communication tools are available. The location of the work and access to emergency services. The nature of the work. The worker’s skill and capabilities. The risk to mental health. Support the worker may need for their tasks. Controlling the risks of lone working You can control the risks around lone working or remote and isolated working: Ensure workers can access clean, safe, and accessible facilities that are in good working order (toilets, places to eat and store things, first aid kits, drinking water etc). Maintain equipment and furniture regularly. Clean workplaces and facilities regularly, taking into account the shift work or type of work, the likelihood of contamination, and how many workers use them. Provide training, support, and supervision, including what to do in an emergency. Restock soap, toilet paper, consumables regularly. Repair any broken equipment, furniture and fittings. Psychosocial hazards and Lone Working Remote and isolated work can increase the likelihood of workers being exposed to psychosocial hazards. The effects of these hazards can be significant if a worker can’t access support or assistance. Some psychosocial hazards include: Lack of support - they can’t ask questions easily or get immediate feedback from supervisors. Workplace violence - Security guards or retail workers working alone at night face the risk of workplace violence Workplace sexual harassment - Risks of harassment from customers and clients towards workers High job demands - Lone workers have no one to share their workload with or divide tasks Low role clarity - Workers can’t discuss and clarify tasks and sometimes have to manage everything by themselves. Psychosocial hazards are equally serious as physical hazards, and they should be handled carefully. Lone workers should have your support, and they should know who to reach out during times of duress. Reducing risks of lone working According to a survey, safety training is a most desirable form of support for lone workers. Mental health comes in a close second, indicating that lone workers are more vulnerable and struggling to cope with their roles. These statistics are indicative of the training and support your lone workers are seeking. As an employer you have few ways to reduce the risks to your lone worker: Train them fully in the risks of their type of lone working. Set up a system of routine communication with them. Provide good supervision. Identify potentially violent situations and use control measures that could reduce or stop lone working. Provide effective emergency procedures. Set up physical barriers to protect them from violence. Offer multiple ways of reaching out (phone, email, text, etc) so they know you are present for them. Create safe workplaces with Peninsula Lone working is a risky and high intensity form of working. For many small businesses in Australia, remote or isolated work is often the norm. However, some business owners and employers don’t realise the responsibilities that come with overseeing and employing remote or isolated workers.
