This organization would be using Simple Random Sampling.
When the selection of which individuals to sample is made randomly from one big list, it is called a simple random sample (or SRS). An example of this would be if a teacher put every single student's name in a hat and then draws 5 names from the hat, without looking, to receive a prize. In an SRS every single member of the population has an equal probability of being selected - every student has an equal chance of getting the prize.
