I thank the Cathaoirleach for the invitation to the ESRI to appear before the committee to discuss its work on sub-minimum wages in Ireland. I am a senior research officer at the ESRI.
The topic of sub-minimum wages has received significant attention in recent years, at both a national and international level. It is currently an active area of policy debate in Europe. Of particular relevance for Ireland was the announcement in 2023 that Ireland was in breach of its labour rights obligations under the European Social Charter due to sub-minimum wage rates being deemed too low to allow a decent standard of living.
When thinking about policy in this area, there are several important points to consider. First, what is the rationale for having age-based sub-minimum wage rates to begin with, and what are the arguments for and against their use? Second, how many employees are in receipt of sub-minimum wages, and what are the typical characteristics of these employees? Third, what are the potential impacts of reforming or abolishing sub-minimum wage rates? To shed light on these issues, I am going to draw on recent research the ESRI published in 2023 as part of the ongoing ESRI and Low Pay Commission research programme.
Before discussing these issues in detail, as has already been said, it is useful to briefly summarise the situation as it currently stands. The minimum wage is currently €12.70 per hour. However, legislation allows employers to pay young workers an age-based sub-minimum rate. Those under 18 can be paid 70% of the full rate, those aged 18 can be paid 80%, while those aged 19 can be paid 90%. Other types of workers are also exempt in legislation from being paid the minimum wage. These include apprentices, people employed by close relatives and prisoners engaged in non-commercial work.
For the remainder of my opening statement, I am going to focus on age-based sub-minimum wage rates as they are of most relevance for the current discussion.
One of the main arguments in favour of sub-minimum wages for young people is to ensure wages are not set at a rate that is so high that employers are discouraged from hiring them. The rationale is that young workers may have less experience and lower productivity than older workers, which should be reflected in lower wages. Another argument in favour of sub-minimum wage rates for young people is to discourage early school leaving. However, previous research in this area suggests that the existence of sub-minimum wages will have little impact on early school leaving rates.
On the other hand, the main argument against sub-minimum youth rates is the equality argument, that there should be equal pay for equal work and age should not be used as a means of discrimination. Indeed, in recent debates on the Minimum Wage (Equal Pay for Young Workers) Bill 2022, it has been argued that sub-minimum wages should be abolished as they contravene equality legislation on the grounds of age-based discrimination. However, regarding the legality of sub-minimum youth rates, it is important to note that the Employment Equality Act 1998 allows for employees to be treated differently in certain circumstances. Anything legal under the National Minimum Wage Act 2000 is not deemed to be age-based discrimination under Irish legislation.
In our 2023 ESRI research on sub-minimum wages, we found that the incidence of sub-minimum wage employment in Ireland is low. We estimated that just 1 in every 140 employees in Ireland is paid a sub-minimum youth rate, which is equivalent to approximately 15,000 workers. Furthermore, while all employees aged 15 to 19 could legally be paid a sub-minimum wage rate, the majority are on higher rates of pay. Regarding the characteristics of those employees in receipt of sub-minimum youth rates, we found that just over half were women, and the vast majority, almost 80%, work in either the accommodation and food or retail sectors. Approximately one quarter work in small firms consisting of fewer than ten employees, while 80% are students.
Abolishing sub-minimum wage rates could, potentially, lead to positive and negative impacts for employees. The positive impact would be that current sub-minimum wage employees would see an increase in their hourly wage. However, abolishing sub-minimum wages could also lead to negative employment effects for young workers. Several published international studies have examined this issue. While some studies find no effects, others find evidence of negative impacts on hours worked and employment among young workers. These effects, however, tend to be quite small.
From an employer’s perspective, abolishing youth rates could see an increase in the wage bills of those employing workers on sub-minimum wages. Our research has shown that these employers are mainly concentrated in two sectors, namely, the accommodation and food sector and the retail sector. In related research we published in 2021, again as part of our ESRI-Low Pay Commission research programme, we found that the majority of employers do not employ minimum wage workers, and among those that do, minimum wage employees tend to make up a relatively small share of the overall workforce. Therefore, while some employers may be more affected than others, the overall direct impact on labour costs of abolishing sub-minimum wages would likely be quite low.
Let me conclude by once again nesting this debate within a wider European context. Minimum wages in the EU are quite common, with 22 of 27 EU countries currently having a statutory minimum wage. Age-based sub-minimum wages, however, are less common. Just one third of countries with a statutory minimum wage use sub-minimum youth rates. The EU directive on adequate minimum wages, published in 2022, states it is important to avoid sub-minimum wage rates being widely used as they risk having a negative impact on the adequacy of minimum wages. Taken together with the finding that Ireland is currently in breach of the European Social Charter, this would indicate that sub-minimum wage policy in Ireland is not consistent with the EU directive on adequate minimum wages. This is also reflected in the recent recommendation from the Low Pay Commission, which in June 2024 recommended the abolition of all sub-minimum wage rates in Ireland.
