The creation of the Social Protection Systems is a relatively recent phenomenon, born of the need to prevent people with disabilities on the grounds that it was to do a job stay in a situation of precariousness and social exclusion. For this purpose we considered various contingencies or motives that could lead to the allocation to such person of a benefit which they serve as support to cope with their situation. This is set as the retirement pension, widow's or incapacity, of which we shall deal in this article. Why is there a work disability coverage? The Disability and Disability coverages Labor were purpose of providing a hedge against those who, having suffered some type of accident or illness (related or not use), are unable to engage in paid work either way temporarily or permanently, unable to access other benefits than the system (eg, having no right of access to that retirement). What is the difficulty that arises when applying for this type of service? An application for permanent disability involves a complex and often uncertain pending before the body managing the Social Security, whose function is basically whether or not the applicant meets the requirements of the Regulations for access to it. Basically, try to verify that: 1 – Meet with the formal requirements established for the specific provision applying, especially if you have met the minimum contribution period required for it. 2 – His health condition is serious enough or precarious after accident or disease to prevent, in whole or in part, to develop a future work.
