International Staff Members (ISM)
Conditions of Employment at ESO
This document summarises the conditions of employment for International Staff Members (ISM) at the European Southern Observatory (ESO).
It is intended for information only to give potential applicants a general overview of the working conditions at ESO. The full details are given in the International Staff Rules and Regulations (SRR) and other official documents, which formally define the working relationship of International Staff Members with the Organisation. On receiving a job offer, applicants will be given copies of these documents.
As ESO is an intergovernmental organisation, its conditions of employment for ISM are independent of German, Chilean, and European Union labour law.
A comprehensive compensation package that supports work-life balance
ESO offers a comprehensive and competitive package of salary, allowances, grants and an attractive social security scheme. In addition, ESO aims to support members of personnel in maintaining a good work-life balance between their professional and private life.
For details of these general aspects of working at ESO, please see the sections “General conditions” and “Work-life balance”.
Creating a family-friendly workplace
ESO is committed to being a family-friendly workplace, creating a work environment and policies which allow staff to balance their professional and private responsibilities through flexible working arrangements and financial support for families.
For details of ESO’s measures to support families, please see the section “Family-Friendly Support”.
General conditions
Duty stations
ESO has establishments, known as duty stations, which are located in:
Germany: Garching bei München
Chile: La Silla, Paranal, Santiago, Sequitor, ALMA Operations Support Facility (OSF)
Duration of appointment
The standard contract for an ISM is for a fixed-term duration of usually three years, and is subject to a successful pre-employment medical examination and to successful completion of the probation period.
Under certain circumstances there is the possibility of contract extension(s), subject to individual performance and organisational requirements, and as defined in the applicable policies and staff rules and regulations. ESO Staff Rules and Regulations apply by analogy to the contract of the Director General (DG) unless otherwise decided by the Council or are incompatible with the position of the DG. Please note that the contract policy and in particular the regulations concerning fixed-term and indefinite contracts are currently under review which may lead to changes in contractual conditions.
Basic salaries
ESO has a salary structure consisting of a series of grades from 2 to 14. Within each grade, there is a series of steps from 0 to 15 (in grades 2 to 4), 0 to 13 (in grades 5 to 12), 0 to 10 (in grade 13), or 0 to 7 (in grade 14).
Initial grade and step, and therefore salary, is determined in relation to the position and a candidate's qualifications and experience, and is set at the time of the appointment.
The basic salary refers to the salary before the deduction of contributions for healthcare and pension scheme, and before the payment of any additional allowances.
The salaries of ISM are reviewed annually by ESO’s governing bodies, and may be adjusted taking into account cost of living changes. The salaries of ISM with duty station in Chile are further adjusted monthly, according to the cost of living differential between Santiago de Chile and Munich.
As part of the annual Performance Management and Professional Development process, and the associated Advancement process, there is the possibility for ISM to progress through the salary step and grade structure.
Due to ESO’s status as an intergovernmental organisation, no income tax is payable for member state nationals. Instead, an internal tax is withheld at source.
Working hours per week
The basic working schedule is 40 hours a week on average. The specific working schedule and hours of work may vary according to the duty station.
Health Insurance Scheme
The ESO health scheme provides private worldwide healthcare insurance for medical expenses of ISM and their dependent family members. The monthly healthcare insurance contribution that the staff member pays is independent of the number of dependent family members.
Long Term Care Insurance Scheme (LTC)
The LTC scheme provides financial support to ISM, and their dependent family members, who are in need of assistance over an extended period of time due to an impairment of their ability to function independently in daily life.
Unemployment Insurance
ISM are entitled to unemployment insurance benefits if they are without employment immediately after their appointments terminate, subject to certain conditions.
If the appropriate conditions are met, unemployment benefit will be paid for up to 6 or 12 months, depending on the staff member’s length of service. This is normally between 70% and 80% of the final basic salary.
Salary during sick leave
An ISM’s salary continues to be paid during absences due to sickness, with certain limits and conditions. If the appropriate conditions are met, including the submission of a medical certificate, the rules allow in the first instance for up to 12 months of sick leave on full pay within a period of 36 months. Additional rules apply after this.
Pension Scheme
The ESO pension scheme, which is part of the CERN Pension Fund, incorporates a defined benefits pension and insurance provisions for death, (occupational and non-occupational) disability and injury. All ISM are compulsorily insured at the time of appointment.
A member of the pension fund with at least five years of service is entitled to a retirement pension. For less than five years of service, a transfer value may be either paid into another pension scheme or paid to the staff member.
The retirement age is 67 years.
The retirement pension is calculated as a proportion of an ISM’s average basic salary during their final 36 months, taking into account other factors including years of service and age.
Although — as described in the Basic Salaries section — no income tax is payable on ESO salaries under most circumstances, the retirement pension may be taxable, depending on the retiree’s place of residence and tax situation.
More information about theCERN Pension Fund is available on its website.
Annual Leave
Annual leave entitlement for ISM is 2 1/2 working days per month (30 days per year). The leave year runs from 1 April to 31 March of the following year.

Home Leave
Once every two years in Garching and every year in Chile, an expatriated ISM is entitled to a home leave return trip to his or her “home station” (typically the staff member’s home state or place of residence at the time of appointment). ESO pays the expenses of the journey for staff and their family within certain limits.
Expatriation Allowance
A monthly expatriation allowance is payable to ISM under certain circumstances. The rate is calculated as a percentage of the staff member’s basic salary, within certain limits.
Mountain Allowance (Chile only)
A mountain allowance is payable to ISM with duty station La Silla, Paranal, Sequitor, or OSF.
- ISM receiving household allowance (see “Family-Friendly Support” section below): 20% of the basic salary
- ISM not receiving household allowance: 10% of the basic salary
The amount of the mountain allowance listed above applies when the regular amount of working time is spent on the mountain. The amount paid is adjusted according to actual time spent on the mountain.
Joining expenses
Newly appointed ISM residing more than 50 km from the duty station before their appointment are entitled to be paid travel expenses for themselves and their families, removal expenses, and an installation allowance. Additional information on the importation of household goods (personal effects, cars, etc.) to the duty station can be obtained from Human Resources.
Initial accommodation for new arrivals
ESO has a few fully furnished apartments (1 room to 3 rooms) in Garching. Subject to availability, these apartments can serve as a temporary solution for newly appointed ISM. The rental period also depends on availability and is usually for a maximum of three months. The cost of the apartment is charged to the staff member and deducted through the monthly payroll.
Newly appointed ISM in Chile are accommodated for free in the ESO Guesthouse for the first night and receive free lodging in a furnished apartment for up to five weeks (35 nights)
German Language Training in Garching / Spanish Language Training in Chile
ESO offers newly appointed ISM and their spouses in-house language training at the beginner’s level. The aim of the course is to provide them with the language skills to help them deal with their everyday life and to settle in to their new environment.

The scheme provides for the possibility to do mobile working up to seven days per calendar month and in addition to 30 additional days per calendar year. Other than when periods of mission or sick leave shall preclude it, staff are expected to work on-site at their duty station for the equivalent of at least five working days per calendar month.
