There are times when your health demands a break, even if only for a short time. The good news is that, in cases of illness, you can justify up to three days’ absence from work without a doctor’s certificate by using the Self-Declaration of Illness (ADD). <\/p>

Find out how it works, how to request it and what other useful features you can find on the SNS 24 Portal and the SNS 24 App.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Self-declaration of illness: what it is<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Self-declaration of illness – also known as “sick leave” – is a simple and practical mechanism designed for short-term illnesses. Without the need to go to the doctor or health center, the employee can justify up to three consecutive days of sick leave by declaring it under oath. <\/p>


This system, valid for people over the age of 16<\/strong>, allows absences to be justified up to twice a year, giving a total of six sick days per calendar year (using two three-day sick days). It’s especially useful for dealing with mild colds, temporary illnesses or other situations that don’t require immediate medical attention. <\/p>


And even if you only need to miss one day, you can ask for a one-day sickness self-declaration.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

You must request a self-declaration of illness within five days of the start of the absence. Please note: as mentioned, you can only use it twice a year, with a maximum of three consecutive days per request. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
