Healthcare coverage is inexpensive and covers most things. Generous paid time off is offered to employees, with the amount increasing substantially the longer you stay. Retirement options through the TSP (Similar to a 401k) are flexible and generous matching is available.
You get to see a specialist without a doctor referral. Your sick and annual leave are separate. Many companies lump them together as PTO.
The worst thing for young professionals is being mandatorily enrolled in the FERS program when it is highly likely that by the time they reach a retirement age the program either expires or goes bankrupt
Great 401K program and a pension.
Thrift Savings Plan has very low fees and government match. Contribute at least 5% of your salary each pay period to get the maximum match.
In one line, benefits here are absolutely phenomenal (salary and compensation up to market standard, however, is terrible). 401k is something called a thrift savings plan (or TSP) and its essentially the same thing as a 401k. Matching is up to 5% of your salary. They actually offer a Roth version, which is great since most employers apparently only offer a traditional one. Also have the untaxed spending account thing for medical-related expenses, which is a plus. You have a very large option of health, dental, and vision insurance available, and there is also life insurance available. The health insurance is REALLY good for how much you pay for it. Starting out fresh, you get 4 hours of paid vacation time and 4 hours of sick leave per 2 weeks, which later increases to 6 hours each, and then to 8 hours each if you stay a certain amount of time (I don't know what the certain amount of time is). You work 9/80 schedule, so you get every other Friday off, so it comes out to "about" a day of leave every 4 weeks. Sick leave can only be used 3 days in a row consecutively before people start asking questions and you need an official reason/note. You also get every federal holiday off - which there is a LOT of them. They usually fall on a Monday, and if the Friday off that week from the 9/80 happens to be the same week, then you can take 3 days off (Tues, Wed, Thurs) and end up having an entire week off plus the weekend days (3 vacation days for 9 consecutive days off, which is referred to as a 3-for-9). You have access to Navy facilities and gym, etc.
401k matching to 5% of salary. Amazing health insurance options. Crazy amounts of time off.
5% match on 401k, plus a pension! vacation starts at 2.5 weeks, then goes to 4 weeks after 3 years, then up to over 5 weeks after 15 years. 2.5 weeks sick time (can be used for doctor's appointments and taken care of newborns) and 10 paid federal holidays. Details can be found on opm.gov
The government makes up for it's average or below average paycheck in numerous ways. Although it's not as fancy as the high tech world there are a lot of benefits that you get which many people in the private sector don't. I almost said yes to about every option I had below.
