As an employee of the Federal Bureau of Prisons, staff are required to work 24 hours a day and 365 days per year including holidays. When staff work a holiday, they are paid accordingly. If you are considered "non-essential staff", normally non-custody staff, you are given the holiday off with pay. If your day off falls on the holiday, you are given an "in lieu of holiday" that either gives you holiday pay or the holiday off for the last work day before the holiday or the immediate day following the holiday. Although this seems like a nice gesture for the employee, it makes more sense and more fiscally responsible to pay only the essential employees working the actual holiday.
