The Pros and Cons of Zero-Hour Contracts.

Zero-hours contracts, also known as casual contracts, have been around for quite some time and have been a topic of debate in the employment world. On the one hand, they offer flexibility and convenience to both employers and employees. On the other hand, they can also lead to uncertainty and instability in the workplace. In this blog post, we will discuss the pros and cons of zero-hours contracts and help you understand whether they suit you.

What are zero-hours contracts?

Zero-hours contracts are employment arrangements in which the employer does not guarantee a minimum number of hours for workers, and the workers are not obligated to accept any hours offered. This type of contract is quite common in industries like hospitality, retail, and care services, where demand fluctuations occur. It is also important to remember that zero-hours staff are entitled to statutory annual leaves and the National Minimum Wage like regular employees. Therefore, the employment status of zero-hours staff will depend on their circumstances. 

Pros of zero-hours contracts

The main advantage of zero-hours contracts is that they offer employers and casual workers flexibility. Employers can quickly meet the changing demands of businesses by bringing in more workers on short notice, while workers can choose the hours they work and the jobs they take. 


One of the most significant advantages of a zero-hours contract is that it offers flexibility to both employers and workers. Workers can work as much or as little as they want, while employers can adjust their workforce according to their needs without committing to a specific number of hours each week. This means that both parties have more freedom in the way they organise.

Lower Costs

Another benefit of zero-hours contracts is that they can help employers reduce their costs. For example, employers don’t have to pay for employee benefits such as health insurance and pension plans, as these are usually not part of the contract. Also, they don’t have to worry about paying minimum wage or overtime since they are not obliged to provide a set number of hours per week.

Ability to manage unpredictable demand

One more benefit of zero-hours contracts is that they help employers manage unpredictable demand. These contracts enable employers to respond quickly to changes in customer demand and adjust the workforce accordingly. This can be particularly useful in the hospitality and retail industries, where demand fluctuates significantly throughout the year. 

Cons of zero-hours contracts


One of the main drawbacks of zero-hours contracts is the lack of predictability for both employers and workers. Employees don’t know how many hours they’ll be working, so it can be challenging to plan financially or arrange childcare or other commitments. Employers also face uncertainty as they may need to hire more staff at the last minute or cut back hours without warning.

Job Insecurity

Another disadvantage of zero-hours contracts is that they can lead to job insecurity as employers are not obliged to provide work weekly, so there is no guarantee of regular income. Workers may have to take on multiple jobs to make ends meet, which can be stressful and tiring.

Limited access to benefits

Finally, zero-hours contracts can limit access to certain benefits that employees working on regular contracts have. This includes paid leave, holiday pay, sick pay and other employee benefits. 

Unpredictable income

Another major downside to zero-hours contracts is that they can lead to unpredictable income. This is because employers are not required to provide the same number of hours each week, so a steady income is not guaranteed. This can make it difficult for employees to manage their finances and plan for the future.

Case studies

Examples of companies using zero-hours contracts

Many companies use zero-hours contracts, including big names like Amazon, Burger King, and Mcdonald’s. 

In the UK, many large companies are using zero-hours contracts. These include Sports Direct, Uber, and DHL. 

Analysis of the impact on employees and employers

The impact of zero-hours contracts can vary depending on the individual case. For employees, this type of contract can offer flexibility and convenience but may also lead to job insecurity and unpredictable income. On the other hand, employers benefit from greater flexibility but must be careful to ensure that their workers are not taken advantage of by unfair working practices.

The legal Framework

What is the employment status of zero-hours contracts?

The employment status of zero-hours contract workers will depend on their circumstances. Generally, a worker’s employment status is determined by their working patterns, pay and other factors such as the level of control over their work and whether there is a requirement for personal service. 

What are the employment rights under zero-hours contracts?

Under the Employment Rights Act 1996, employees have certain rights regardless of their work hours or working pattern.

Holiday pay: 

All workers are entitled to holiday pay on casual contracts. In addition, employees accrue annual leaves from the first day of their employment.

Rest breaks: 

People working on zero-hour contracts are entitled to one uninterrupted rest break for twenty minutes every six hours.

Sick pay: 

Hourly staff get sick pay but under limited conditions. Staff are only entitled to SSP for the days they would have been scheduled to work and don’t get it for the first three days they’re off. They must also have earnt an average of at least £120 per week (before tax) in the past eight weeks. 

Maternity and Paternity leaves: 

To receive statutory maternity or paternity pay, the employee must have been earning at least £112 per week on average and have been employed continuously for at least 26 weeks by the 15th week before the baby is due. If a staff member doesn’t receive any shifts for a whole calendar week – seven consecutive days from Sunday to the following Saturday – this usually counts as a break in employment. Therefore, if an employee has a one-week break during a certain period of their pregnancy, they may no longer be entitled to maternity pay.

Redundancy pay: 

Hourly staff are entitled to redundancy pay if they have worked continuously with an employer for two years or more. The statutory redundancy pay is calculated based on length of service and weekly wage, up to a maximum of £538.

Notice periods: 

Under employment law, any worker employed for more than one month is entitled to notice before employment ends. This usually applies to regular staff, but there is some discrepancy between what’s expected of those on zero-hour contracts. It’s best to refer to the employment contract, which should explain the notice terms.

Are zero-hours contracts legit?

Zero-hours contracts are legal in many countries, including the UK and US. However, it is essential to note that the law may vary depending on where you live and the laws in your jurisdiction. It is also crucial to ensure that workers on zero-hours contracts are treated fairly and not exploited by employers.

Overview of relevant labour laws

Different countries have different labour laws when it comes to zero-hours contracts. In the UK, for example, there is no legal limit on the number of hours a person can be asked to work or the amount of notice they must be given. Employers also do not need to provide benefits or pay the National Minimum Wage if the worker has agreed to a zero-hours contract.

Discussion of recent legal cases

Several legal cases have been brought against employers who have used zero-hours contracts. For example, in 2019, an employment tribunal found that Sports Direct had acted unlawfully by failing to properly pay workers on zero-hours contracts for their overtime and holiday pay. Similarly, in 2020, a high court ruling found that Uber had incorrectly classified its drivers as self-employed rather than workers entitled to the minimum wage and other employment rights.

How does it defer from fixed-term contracts?

Fixed-term contracts differ from zero-hours contracts in that they guarantee a certain number of hours or salary. As such, employers must provide employees with the agreed-upon hours each week, regardless of demand. Additionally, employees on fixed-term contracts are entitled to the same rights as regular employees, including paid leave, holiday pay and other benefits.

How does it differ from part-time contracts?

Part-time contracts differ from zero-hours contracts in that they guarantee a set number of hours each week. As such, employers must provide employees with the agreed-upon hours each week, regardless of demand. Additionally, employees on part-time contracts are entitled to the same rights as regular employees, including paid leave, holiday pay and other benefits.

What is the position of the government on this type of contract?

The UK government has been increasingly vocal in its opposition to using zero-hours contracts. In 2015, the government introduced a ban on exclusivity clauses in zero-hours contracts, which prevented workers from working for other employers. The government also launched a review of the use of these contracts and proposed measures to ensure that workers are not taken advantage of. 

What is the position of trade unions on this type of contract?

Many trade unions have expressed their concerns about the use of zero-hours contracts. Unions are particularly worried that these arrangements can lead to worker exploitation and insecurity. However, trade unions have also welcomed the government’s review of zero-hours contracts and called for further action to protect workers.

Zero-hours contracts have their fair share of advantages and disadvantages. On the positive side, zero-hours contracts offer flexible working hours. Employees are free to work as much or as little as they want, which is especially beneficial for those with other commitments or responsibilities. Additionally, employers can save on labour costs, as they only pay employees for the actual hours worked. However, on the negative side, the unpredictability of zero-hours contracts can make it difficult for employees to plan their lives around work schedules. In addition, employees on zero-hours contracts may not receive the same benefits and rights as those on standard contracts, such as sick pay or maternity leave. As a result, zero-hours contracts are a controversial issue, with opinions divided on whether they are beneficial or exploitative.
