Good. If one did the same for any private company, they too would get fired.
She's doing what her predecessors did not -- weeding out the people living high on the public trough and not doing what they are paid to do.
Behavior like this starts at the top, either because they ignore the problem holding nobody accountable, because they enable it by hiring more people to do the work those people are not doing, or both.
She said it's over 100 people.
Let's assume they each spend 2 hours/day on sex chat. The Office of Personnel Management uses 2,087 hours as the number of work-hours in a year. 2,087 / 9-hr workday = 231.888 days per year. Most salaried federal jobs require 9 hours of which 1 hour is for a lunch break.
Rounded to 232 days, that's 232 x 2 hrs per day = 464 hrs per year per person x 100 people = 46,400 hours cumulatively spent on chat in a single year. then you have to multiply that by the number of years on average they were wasting time on sex chat to get the full depth of fraud and waste.
46,400 hours per year represents about 22 full time employees. In other words, those 100 or so employees are doing the work of about 88 people -- but we are paying for 100 people's salaries, benefits, administrative overhead, training, equipment, office space, etc.
