You get five weeks paid holiday a year. As it is a small company it can’t afford to have too many people off at once which means, if someone has booked the time off that you want then sadly you may not get it off, there are occasions where it’s quite and multiple hosts can be off at once and there have been times when I’ve swapped my holiday with others in order to get the days off I need. As for booking time off, taking a week block is ideal for holidays abroad and larger plans but I’ve also been able to book a weekend off here and there on quite occasions.
You cannot book indivual days off. they make you take weeks off at a time which doesn't fit around a scheldal if you want to take off only 3 days.
