800 employees, want to sample 10%, so the sample size will be 80.
You want a representative sample with the same proportion of workers as the whole population.
Take 10% of each of the different positions:
10% of 100 = 10 executives
10% of 650 = 65 middle managers
10% of 50 = 5 custodial workers
So pick 10 random executives, 65 random middle managers, and 5 random custodial workers. That way your sample is representative of the population.
