Chapter 4: Data and Methodology
4.2. Measuring top occupations – data and sample
As argued in Chapters 2 and 3, previous studies linking gender labour market inequalities with family policies and labour market institutions, have focused firstly on aggregate data on the macro-level indicators, such as employment rates, and secondly on women of all educational backgrounds. In contrast to employment rates, vertical segregation cannot be explained by prevailing welfare regime typologies, and has been widely neglected by labour market researchers for the sake of the pay gap. Vertical segregation in this paper is examined by comparing o e s likelihood to be in managerial and senior professional occupations relative to e s.
By using this different definition of vertical segregation based on individual-level data and individuals with tertiary education only, this thesis therefore takes a different methodological approach than previous studies. The following section summarises how vertical segregation is measured. Then, the rationale behind using individual-level data over aggregate macro-level data is explained in greater detail in section 4.2. For clarification, this thesis expands the regular definition of managerial positions by adding senior professional occupations. Whilst the rationale for this will be explained below, for the reader, the occupations included are mentioned at this point.
Managerial occupations include:
➢ Chief Executives, Senior Officials and Legislators; ➢ Administrative and Commercial Managers; ➢ Sales, Marketing and Development Managers; ➢ Hospitality, Retail and Other Services Managers
Senior professional and managerial positions include the listed occupations above, as well as:
93
➢ Science and Engineering Professionals;
➢ Health Professionals (excluding Nursing and Midwifery Professionals and others health professionals);
➢ Teaching Professionals (only including Higher Education Teachers); ➢ Business and Administration Professionals;
➢ Legal, Social and Cultural Professionals
Examining vertical occupational inequalities, two issues need to be addressed: firstly, the use of either macro- or individual-level data and secondly, observing the distribution of women across occupational levels or more specifically o e s access to top positions in the labour market relative to e s. This dissertation examines the latter – o e s access to high-status occupations (see Schaefer et al., 2011), often referred to as the glass ceiling (see for example Baxter and Wright, 2000; Fernandez, 1998; Cotter et al. 2001) using individual- level data.
Using individual-level data also allows the researcher to distinguish between occupational levels. This is particularly useful as this thesis does not aim to answer what makes women choose one occupational level over the other, but rather what hinders women from reaching top positions compared to the chances for men. This is of crucial interest, as top positions do not only represent status, but also power and earnings. When referring to women in top positions, this thesis applies the concept of the glass eili g ; as described by Cotter et al. (2001), this term refers to gendered differences in terms of levels of authority and positions in the corporate hierarchy.
From the European Working Conditions Survey 2010, the dependent variable derived from the variable measuring espo de ts is occupation levels. This variable follows the International Standard Classification of Occupations (ISCO-08) by the International Labour Organisation (ILO). ISCO-08 is preferred over the older definition ISCO-88 because ISCO-08 distinguishes general managers and corporate managers in greater details by dividing them
94
into 12 administrative and commercial managers; 13 Production and Specialised Services Managers; 14 Hospitality, Retail and Other Services Managers. Secondly, supervisory occupations are now classified following the nature of work more closely, in order to highlight potential differences between work done by supervisors on the one hand and supervised workers on the other hand (ILO, 2012). According to ISCO-08, jobs across different establishments, industries and countries are hereby grouped according to the nature of the work in a comparable framework. At it s most aggregated level, ISCO-08 distinguished between:

As highlighted previously, this thesis aims to investigate the gender gap in top positions, or in other words o e s relative likelihood to reach top positions compared to e s. In order to capture hierarchies between the occupational groups, we need to look closely at the composition of the so-called 1-digit ISCO groups and focus here mainly on the first two groups – managers and professionals, as they include the jobs requiring the highest skill and therefore qualification levels (ILO, 2012). Managers at 3-digit disaggregated level include the following occupations:
95

11 Chief Executives, Senior Officials and Legislators 111 Legislators and Senior Officials
112 Managing Directors and Chief Executives 12 Administrative and Commercial Managers 121 Business Services and Administration Managers 122 Sales, Marketing and Development Managers 13 Production and Specialised Service Managers
131 Production Managers in Agriculture, Forestry and Fisheries 132 Manufacturing, Mining, Construction and Distribution Managers 133 Information and Communications Technology Services Managers 134 Professional Services Managers
14 Hospitality, Retail and Other Services Managers 141 Hotel and Restaurant Managers
141 Other Services Managers
As mentioned earlier, ISCO-08 in contrast to ISCO-88 focuses more on the nature of work in order to highlight potential differences between work done by supervisors on the one hand, and supervised workers on the other hand (ILO, 2012). Therefore, employees with supervisory duties that distinguish them clearly are included in the major group with managers in the following areas: Manufacturing, construction, mining, retail, cleaning and housekeeping, farming and administration. However, for the purpose of this thesis, which to some extent follows the Human Capital argument, not simply managerial positions seem relevant, but rather employment relations and conditions. Thus, both immediate rewards in terms of the salary and long-term or prospective benefits such as career opportunities are relevant. A useful tool in order to distinguish occupations within the same ISCO-08 group is the European Socio-economic Classification (ESeC) that divides occupations into classes. Class 1, called highe sala iat , captures large employers, higher-grade professionals, as well as administrative and managerial occupations. Contracts are distinguished according to extent e plo ees work may be monitored and controlled, and how specific skills and knowledge of technical and organisational tasks are to the employer. Applying this concept to the ISCO-08
96
managerial occupations only and therefore leaving out P odu tio and Specialised Service Ma age s , leaves us with the following occupations that we can identify as class 1:

However, for three reasons, this thesis also includes senior professional occupations in its dependent variable. Firstly, according to ESeC, not only managerial occupations fulfil the criteria of the higher salariat, but also certain senior professional occupations, such as lawyers or university teachers. Secondly, from a rather technical point of view, there is an already an existing overlap between the main g oup s managers and professionals, as it is sometimes
97
hard to decide whether specific skills are required at the legislative, administrative or managerial level, or whether skills need to be directly applied. This leads to problems in the ISCO, but also illustrates the second reason for including both major groups. This paper aims to examine whether generous family policies hinder women from reaching the top. The hypothesis here is that firstly, in generous welfare states, employers are more reluctant to hire women due to the potential of career interruptions and the loss of investment. However secondly, women in countries with less generous family policies are more reluctant to accumulate specific skills that would qualify them for top positions, if work-family reconciliation policies are not available. Thus, not only hierarchies in terms of power are important, but also the level of qualification needed for a specific occupation. Consequently, this thesis includes both managers and senior professionals as to a large extent the latter requires skills at the top ISCO skill level. The following occupations are captured by main group 2 professionals:

Based on ESeC, but also on the classification if ISCO-08 itself, we cannot consider all occupations in this category as a top position. According to the ILO, one of the achievements of ISCO-08 compared to ISCO-88, is to also acknowledge the nature of the work and not only
99
qualification levels. While this makes sense from an empirical perspective, it is problematic in order to test the skill investment and recruitment argument. Since we are interested in whether family policies create barriers, as employers might be more reluctant to hire and train women for highly skilled jobs due to expected career interruptions, the nature of work matters, but more than this, the level of skills required also matters. The ILO (2007) highlights that for two sub-groups in the main group, professional occupations with the same nature of work, but different skill levels, are classified as professionals – that is teachers and health professionals. However, since for example qualifications for primary teachers clearly differ from those for university teachers, or between professionals and associate professional nurses and midwives, it was decided to not include nursing and midwifery professionals and teaching professionals with the exception of university and higher education teachers from the dependent variable. Thus, primary, secondary and vocational education teachers are not included. This also corresponds with the ESeC recommendations (see also Rose and Harrison, 2007). In addition to this, ESeC also excludes librarians, archivists and curators; social work and counselling and religious professionals; authors, journalists and linguists; creative and performing artists. This leaves us with the following professional occupations in addition to managerial occupations listed in table 4.5 for class 1:

In order to grasp whether family policies only affect o e s likelihood to reach powerful positions that require high qualifications, or whether they also affect o e s chances to reach high-skilled jobs in general, all models are tested both for the dependent variable being managers and professionals, and just managers. Managerial positions include Chief Executives, Senior Officials and Legislators; Administrative and Commercial Managers; Sales, Marketing and Development Managers; Hospitality, Retail and Other Services Managers (see table 4.3). Professional and managerial positions include the aforementioned ones in addition to Science and Engineering Professionals; Health Professionals (excluding Nursing and Midwifery Professionals and others health professionals); Teaching Professionals (only including Higher Education Teachers); Business and Administration Professionals; Legal, Social and Cultural Professionals [as listed in table 4.4]. For both dependent variables, a dummy variable is created with top positions being 1 and all others being 0. Table 4.6 illustrates the descriptive statistics for both dependent variables.

To summarise, the author applies both the regular definition of managerial positions and additionally a wider definition of top positions that also includes senior professionals. Both definitions follow the idea that senior professionals for the purpose of this research are to be treated similarly to managers. This is because both managers and senior professionals as listed in the paragraph above, both have similar characteristics such as a lower risk to be made redundant, less short-term fluctuation of income, a better prospect of a rising income, greater security, greater authority and control over employees (Rose and Harrison, 2007). For example, a retail manager is expected to have comparable levels of security, chances of career progression, authority and control as a senior business and administration professional. Consequently, adding senior professionals to the definition simply widens the definition of top positions and should be considered as complimentary to the existent definition of managerial positions. This is why in the course of this thesis both definitions are used interchangeably, especially because from a methodological point of view, the wider definition of top positions also offers a greater sample size.
