Between imposing and encouraging vaccination – factors that employers should consider

Vaccination of employees is a topical and emotive issue in Hong Kong currently as government statistics show that take-up has been slow. Many employers are exploring their options as they seek to provide a safe workplace and resume full operations, especially businesses in the airline, hospitality and food and beverage sectors which have suffered greatly during the pandemic and the associated restrictions.

The Hong Kong Football Club was recently in the news for its reported announcement that employees potentially could forego promotions, bonuses and other benefits unless they are vaccinated. Other companies have intimated that cutbacks and redundancies may occur if staff do not take the jabs. Almost immediately the Equal Opportunities Commission cautioned that while providing incentives to encourage vaccination was acceptable, the removal of benefits could potentially lead to disputes.

Against this background, we discuss the factors that employers should bear in mind when considering the next steps regarding their approach to vaccination.


The vaccination programme in Hong Kong aims at safeguarding public health to eventually allow a return to normalcy in public activities. The government has offered Pfizer-BioNTech and Sinovac vaccines free of charge to all Hong Kong residents who are aged 16 and above (“Vaccination Programme”), with new guidelines for children as young as 12. Despite the ease of access to the vaccines and availability of information on the government website, there has been a general reluctance towards the Vaccination Programme. The take-up rate has been low and the percentage of the population who are fully vaccinated is far from the 70% threshold which the government is aiming for. The general reluctance and lack of clear guidelines present a dilemma for employers seeking to provide a safe working environment while preserving business interests.


Although there is no law that prevents employers from requiring employees to get vaccinated, the way employers choose to encourage may potentially present a variety of legal and practical difficulties.

Pursuant to Section 6 of the Occupational Safety and Health Ordinance (Cap. 509) (“OSHO”), as far as reasonably practicable, employers are required to ensure the safety and health of all employees in addition to a common law duty to take reasonable care. Employees also have a corresponding statutory duty to co-operate, alongside a common law duty to obey lawful and reasonable orders of their employer.

While there is an argument that requiring employees to be vaccinated would be aligned with an employer’s duties, ultimately there is no certainty regarding whether mandating vaccination would amount to a ‘reasonable’ measure for ensuring safety and health at the workplace. This will likely depend on factors such as the efficacy and safety of the vaccines, the nature of the employee’s role, the health and safety risks present at a specific time (such as the number of cases and deaths), and the employee’s reasons for refusing vaccination, as well as whether there are available alternatives to vaccination (such as masks and regular testing). Mandatory vaccination may be a reasonable measure, for instance, in high-risk sectors such as food and beverage, and healthcare, where there is significant interaction with the public and specific government requirements regarding the minimum number of vaccinated staff apply. However, there is no one-size-fits-all approach and employers will need to make exceptions for employees who should be exempted from vaccination based on medical grounds and other conditions.

Employers should also bear in the mind the possible legal consequences under the Employees’ Compensation Ordinance (Cap. 282), which may entitle an employee to compensation for "personal injury by accident arising out of and in the course of the employment" if they suffer illness or other effects through mandatory vaccination.

There are also potential discrimination issues. The definition of “disability” under the Disability Discrimination Ordinance (Cap. 486) is broad and includes medical conditions. Similarly, there could be potential claims of direct or indirect discrimination under the Sex Discrimination Ordinance (Cap. 480) (on grounds of pregnancy or breastfeeding) unless relevant categories of staff are exempted from any company policy that all employees must be vaccinated.  


Given the legal and reputational risks associated with mandatory vaccination, there has been a significant focus on encouraging or incentivising employees to get vaccinated. The forms of encouragement range from open dialogues with employees - to address perceived concerns about the safety of vaccines and emphasize the local and wider societal benefits of vaccination - to financial and other incentives.

These incentives include bonuses and one-off payments, flights, staycations, tickets to theme parks, vouchers and coupons for shops, restaurants and films, as well as lottery tickets. The chance to win a flat worth HK$10.8 million in a lottery for those who are fully vaccinated has caught the collective imagination. Employers are also offering employees additional leave if they get vaccinated and/or time off during work hours, as well as transport allowances/reimbursement to get to vaccination centres.

At this stage, it appears that financial incentives have the biggest impact and employers need to consider what is likely to be most influential for their specific workforce. In devising incentives, however, employers should focus on persuasion and encouragement rather than pressure or duress. Taking into account the EOC’s pronouncement, employers should avoid removing benefits and entitlements that employees are otherwise entitled to. Similarly, companies should be cautious about policies that provide that only vaccinated staff will be considered for promotions or pay rises. Incentives should focus on encouragement and specific targeted rewards, rather than duress and the threat of removing entitlements.


In most cases incentives (if any) are only being offered and provided upon proof of vaccination. While there is no prohibition on monitoring the vaccination status of employees, employers should keep in mind that they are required to comply with the requirements relating to collection, use, handling, storage and deletion of personal data under the Personal Data (Privacy) Ordinance (Cap. 486) (“PDPO”).


Given the complexities and the rapidly changing situation surrounding COVID-19 employers are faced with a delicate balance between securing business interests and workplace safety on the one hand and employee concerns and associated risks on the other. Employers should carefully consider the legal implications of requiring employees to be vaccinated before implementing policies in this area. With all the sensitivity involved, clarity and consistency of communication with employees play a vital role in this process.
