What is Subsídio de férias?
In addition to normal salary during holidays, the worker is entitled to the subsídio de férias (holiday subsidy), equal to one month of base pay and seniority supplements (diuturnidades), for each year of work.
In the first year it is counted proportionally. The subsidy can be paid in full before the holidays or in duodécimos (twelfths) over the year.
In practice
A worker with €1,500 of pay receives, once a year, another €1,500 of holiday subsidy (or €125/month if they opt for duodécimos).
