Holidays in first year of full-time work?

Yes it is true but check with your employeer to be sure about the amount of days. But yes, european leave is a real thing for workers who can't get “normal holidays” during their first year. Be aware that you wont get paid for these days.

You can read up on holiday leave HERE

I can give you my experience i took European holidays. Normally i got paid for them in my salary. But the money got deducted later from my holiday bonus which normally paid in may or june. So best is check with your HR or admin team.

This is not correct: employees do get paid for each European holiday (= supplementary holiday) they take.

It is the equivalent pay as a working day.  However, it does affect the amount of double holiday pay that is paid out in the next year N+1. The double holiday pay is based on the number of days worked in year N and the number of days of statutory leave.   With a European holidays not being the equivalent of a day of statutory leave taken in Year N, the European holiday will not count as a day of statutory leave.  Therefore, this European holiday is not taken into account when calculating the amount of double holiday pay in N+1.
