Insight: 80% work for 100% pay – what manufacturers need to know about the four-day working week

A new report by the CIPD has revealed that a third of employers think the four-day working week will become a reality for most UK workers within the next decade. According to lawyers at Irwin Mitchell , many manufacturing businesses are exploring their options in this area, but as Charlotte Sloan points out, there’s a great deal to consider.

The idea of working fewer hours for the same pay isn’t entirely new. Between 2015 and 2019, Iceland conducted trials that took place in schools, the police force and government departments to understand the impact of working fewer hours on employee productivity and wellbeing.

In June this year, the UK launched its own six month trial of the four-day working week which involves 70 organisations and is the largest ever trial of its type anywhere in the world. UK employers and workers engaging in the pilot have access to workshops, mentoring, networking, wellbeing and productivity assessments to support and assess the impact of the trial.

However we’re already seeing an interest in exploring adopting a four-day working week for employers who aren’t involved in the trial – including some in the manufacturing sector.

So what’s the appeal for employers?

Many employers are struggling to fill vacancies. Unemployment is at a record low and competition for talent at an all-time high. And, employees whose skills are in demand are becoming increasingly choosy about which offer to accept, with many opting to work for those organisations with strong environmental, social, and governance (ESG) credentials.

Many employees want to work flexibly and it’s becoming common to see many roles advertised as hybrid. But it’s not just about being able to work from home; increasingly employees want employers to take active steps to support their health and wellbeing. Reducing the amount of time they are required to work without reducing their pay is likely to score highly on most people’s wish list (what’s not to like from an employee perspective?) and make it easier for you to attract and retain staff.

We are also in the middle of a cost of living crisis and employers are being asked to make significant pay increases to offset inflationary price increases. Adopting a four-day working week model will give staff a real terms pay increase (working fewer hours means that their hourly rates will increase), plus they will save money if they ordinarily travel to work.

Can the four-day week really work?

The Icelandic study found that shift workers benefitted slightly more than workers during the trials but all groups saw an improvement in their overall wellbeing. They found it easier to balance their work alongside their domestic responsibilities and had more time to spend on exercising, hobbies and seeing friends and family. But the big reveal was that productivity wasn’t impacted, regardless of the type of work involved and, the reason for this, according to the co-author of the report, is that people “unquestionably waste hours at work”.

But there are drawbacks too:

1 – Allowing staff to work shorter working hours without reducing their workloads, could increase the pressure and stress on employees that already work productively and efficiently. A particular challenge may be reducing the working time of part-timers workers when the hours available to fulfil their role are already tight.
2 – You may have to manage a more complex array of working patterns, if you can’t simply shut down your workplace one day a week, or employ other staff to cover this (which will increase your overheads unless you raise productivity too). This happened in the Icelandic study where the government had to hire more healthcare workers to provide cover due to shorter working hours.
3 – What will you do if you can’t maintain the productivity you need to remain profitable, or otherwise meet customer demand?

Alternatives to the four-day working week

It’s clearly not going to be easy for all employers to adopt a four-day working week. But there are other alternatives which should still improve employee wellbeing without having a negative impact on the service being delivered. For example, your business may:
implement a working pattern of nine out of ten days, or working half a day rather than a full day one day each week;
reduce all employees’ daily working hours – even if only by an hour or two; or
introduce flexible working policies that move employees from their rigid working patterns and give them the freedom to get their job done at a time that works for both you and them.

Three tips to help you reduce working time without impacting performance

1 – Communicate with your staff

If you are going to trial reducing employees’ working hours, you’ll need to get your staff on-board and discuss with them how you envisage it working, what your expectations are, and how you will determine if the trial has been a success. Clear and honest communication is key. You’ll need to consider what model you want to trial and then ask staff for their feedback and suggestions about how to make it work.

If you are not going to offer a shorter working week to all staff you will also need to think about how it’s likely to go down with those who aren’t involved who will be working more hours than their colleagues on less pay. Will you pay them an additional allowance to compensate them or rotate the trial so that everyone experiences it, albeit at different times?

You may also need to review and make changes to your working practices. Talk to your staff as they may be able to identify easy time savings that you can implement quickly and easily. If you recognise a union for collective bargaining, you will need to consult with them to try and agree the changes you propose.

2 – Implement trial periods and get the contract right

There is no guarantee that the four-day working week will work for your organisation. You must reserve the right to require staff to revert to their usual working pattern after the trial so that if productivity significantly falls (or the trial fails on any other metrics you intend to use) you can do just that.

This requires a temporary change to your employee’s terms and conditions of employment. You don’t have to issue a new s1 statement or contract of employment, but you must explain in writing to each employee, how long the trial will last, how much the employee will be paid and any other relevant information.

3 – Work out how to maintain or increase productivity

There are a number of measures that can be put in place to increase employee productivity including:
encouraging employees to switch off e-mail or other notifications when working on a large task and setting aside certain times when they can be disturbed;
supporting employees to be more productive by identifying their individual working style. For example, the Pomodoro Technique encourages staff to deeply focus for 25 minutes and then take a five minute break. But that won’t work for everyone. There is a very useful (and free) tool to help staff identify their ideal productivity model which you can access here;
having a ‘no meetings’ day once a week to allow employees to focus on the work they have in front of them and more generally to keep meetings to a minimum;
ditching routine tasks that provide little benefit; and
encouraging staff to get together at lunch time and during any other scheduled breaks rather than at the “water cooler”.
