Job Search

A Jobclub is a place where unemployed people work at finding a job in a professional and systematic way. The first Jobclubs were opened in North America in 1984. Jobclubs take a positive stance: there is a job available for each person. Jobclubs provide people who are unemployed for 26 weeks or more with facilities to enable them to find the best possible job within the shortest time. Executive and Management Jobclubs are also available in some areas, which provide support for middle and senior managers. The Work Trials offer an employer a period of up to 15 days to observe the jobseeker within the workplace. They also give the jobseeker the opportunity to demonstrate their skills and experience to the employer.
Jobplan Workshops are to help people who have been out of work for 12 months or more and to back into work or training. Jobplan Workshops give priority access to education programmes.
Job Review Workshops help unemployed people who are looking to broaden their job search. These workshops are particularly suitable for people with professional, executive and managerial backgrounds. They are demanding for unemployed managers, professional and executives. Participants have the benefits of a computerized guidance system to help them select the most suitable jobs.
A CV (curriculum vitae) – the “story” of your working life – is essential if you’re applying for a new job or position within your own company. Some information might be given in your CV, some in your letter of application. There are no fixed rules about this: different companies have different practices.
