4.4.6. Control variables
Four variables were controlled for in the analysis. The first is a dichotomous
variable relating to union presence, that is, whether or not a union is present. The
second variable relates to the size of the hotel, with dummies for hotels between 25
and 49 employees, 50 and 99 employees, 100 and 199 employees and 200 or more
employees being included within the regressions (the omitted category being hotels
with between 1 and 24 employees). The third variable relates to whether or not hotels
are Barbadian or foreign-owned. The fourth variable concerns the age of the hotel.
