Key Contact: Claire Knowles

Author: Adam McGlynn

After a year unlike any other, our employment team look back on some of the most impactful changes and updates from 2021. You can also find some the following topics covered in our mid-year round-up ‘Employment Law Update: What You Need To Know and What You May Have Missed’.


Over the last 12 months the majority of the UK’s population has been vaccinated against COVID-19. Employers have faced uncertainty along the way in terms of whether such vaccinations can be mandatory, whether employee vaccination status data can be collected and processed, and how to prepare and implement vaccination policies. As one of the most frequently queried topics of the year, our employment team have published a number of articles over the year, including our most recent one on mandatory vaccinations for care home and frontline NHS staff. For all our articles on Vaccinations, please visit:

Though concerns of further COVID-19 restrictions still loom, the UK has been successful in re-opening businesses, services, and venues across the board. Acuity have been on hand to support businesses seeking to understand how to operate within the relevant restrictions as they have changed throughout the year.

Furlough Leave

Until 30 September 2021, the Coronavirus Job Retention Scheme continued to provide a vital lifeline for businesses and employees who would otherwise face redundancies as a result of the economic impact of the Coronavirus pandemic. Our team have provided updates on the changing scheme details over the last two years and, in recent months, we have seen case law begin to emerge on how scheme use by different businesses is being interpreted by tribunals.

Alongside business restrictions and commercial concerns, health and safety concerns have been prevalent as staff have gradually returned to the workplace. Our team have examined to what extent it is reasonable for employees to refuse to return to work, and the extension of this protection to workers in the following articles:

Flexible Working

The Coronavirus pandemic has been a cultural and technological catalyst towards more flexible working arrangements. With flexible working requests becoming more frequent, and cases such as Thompson v Scancrown demonstrating the potential consequences when such requests are poorly managed, it is more important than ever for employers to understand their obligations. Watch this space to see how flexible working rights develop in 2022:

Immigration and Right to Work

2021 has seen the UK transition away from freedom of movement for EU citizens and the introduction of new immigration rules. Considering immigration issues on recruitment and conducting compliant right to work checks have been at the forefront of employers’ minds, particularly since the deadline for EU Settlement Scheme applications expired on 30 June 2021.

Fire and Rehire

With case law updates and ACAS publications providing guidance on how the practice will evolve in the near future, this is definitely a topic to watch for 2022:
