one sided t-test with R. Problem with "less" and "greater"

General
1

I would like to compare the means of two groups.
I am not sure if I have to use "less" or "greater" in my code

I have the following two hypothesis:
The job satisfaction of group 17 is higher than the job satisfaction of group 12

Hypothese 2:
The intention to quit of group 17 is lower than the intention to quit in group 12.

Which code to I have to use for those hypothesis?
t.test(data$pv1~data$IND, alternative="less")
t.test(data$pv1~data$IND, alternative="greater")
t.test(data$PR2~data$IND, alternative="less")
t.test(data$PR2~data$IND, alternative="greater")

pv1 = job satisfaction
PR2 = intention to quit
IND: inclues 2 groups (group 12 and group 17)
