Nearly half of all Greeks are concerned about losing their jobs in the next 12 months, according to a survey made public yesterday, which also highlighted the low level of job security that exists throughout Europe. A questionnaire released in 15 countries by employment service provider Manpower showed that 45 percent of Greeks think they could be out of work in the coming year. The figure is low compared to European countries such as Spain, where 70 percent of respondents said they are concerned about job security. In Austria, those questioned were more optimistic about their career future: Only 30 percent said they were worried about losing their jobs. The survey also showed that only about a third of Greeks believe they will have enough money to leave the work force when they retire and draw pensions. The survey also reflected a demographic problem developing in the country – a low birthrate. About three in 10 respondents said they do not have the financial means to take a break from work to have a child, while 26 percent said children hurt careers.
