5 Cybersecurity Implications of a Four-Day Working Week

The four-day working week is gaining attention as businesses look for ways to improve productivity, support employee wellbeing, and offer greater flexibility. For employees, the appeal is obvious. An extra day away from work without necessarily sacrificing their salary sounds like a pretty good deal.

However, changing the working week involves more than rearranging meetings and adjusting deadlines. Businesses also need to consider how a shorter schedule could affect their technology and cybersecurity.

With employees potentially working different days, accessing systems outside normal hours, and relying more on digital tools, several security considerations are worth exploring.

1. Different Working Patterns Can Make Security Monitoring Harder

In a traditional Monday-to-Friday workplace, IT teams generally know when employees are expected to be online. A four-day working week can make things less predictable, particularly when businesses introduce staggered days off.

Some employees might work Monday to Thursday, while others take Wednesday off and work Friday instead.

This makes it important for businesses to distinguish between legitimate activity and unusual behavior. Someone logging in on a Friday might be perfectly normal, but an unexpected login from an unfamiliar location could still require investigation.

Security monitoring should reflect actual working patterns rather than relying entirely on fixed office hours.

2. Employees May Be Tempted to Take Shortcuts

A shorter working week doesn’t always mean less work. In some businesses, employees are expected to complete roughly the same workload in fewer days.

As deadlines approach, convenience can sometimes take priority over security.

Employees might share files through personal accounts, approve access requests without proper review, or use unauthorized applications to finish tasks faster.

Businesses can reduce these risks by making secure processes straightforward. Complicated login procedures and unnecessarily restrictive systems may encourage employees to look for alternatives.

3. Cybersecurity Needs to Work Even When the Office Is Closed

What happens if a cyberattack takes place on a Friday when most employees aren’t working?

Cybercriminals don’t follow a company’s timetable, and security incidents can happen at any time.

Businesses introducing a four-day week need to think carefully about who will respond to alerts, investigate suspicious activity, and coordinate recovery efforts outside normal working hours.

Using a SASE platform can help businesses bring together network security and secure access capabilities, supporting consistent protection regardless of where employees are working.

However, technology alone isn’t enough. Clear incident response procedures and appropriate monitoring arrangements are still essential.

4. Handover Days Could Create Unexpected Access Problems

Not every company adopting a four-day week closes completely for an extra day. Some maintain five-day operations by allowing employees to take different days off.

This can create challenges when colleagues need access to information or systems managed by someone who isn’t working.

For example, an employee might need an urgent document from a colleague’s account. Without a proper process, they could be tempted to share passwords or use another person’s login details.

Businesses should establish secure handover procedures, shared document locations and appropriate access permissions so work can continue without compromising security.

5. IT Maintenance May Need a New Schedule

Software updates, security patches and system maintenance are often scheduled around quieter periods of the working week.

A four-day schedule could shift when those quieter periods occur.

A business that closes on Fridays might see this as an opportunity to carry out maintenance without interrupting employees. However, if IT staff are also unavailable, unexpected problems could remain unresolved until Monday.

Automated updates, planned maintenance windows, and clear responsibilities can help businesses protect essential systems without disrupting the shorter working week.

Making a Shorter Working Week Secure

A four-day working week doesn’t automatically create more cybersecurity risks. In fact, businesses that plan the transition carefully may find opportunities to improve outdated processes and strengthen their digital security.

The key is to recognize that changes to work patterns can affect how employees access information, how incidents are handled, and when systems are maintained.

By considering these issues before introducing a shorter week, businesses can give employees greater flexibility without overlooking important security responsibilities.
