Pros
Great benefits including 12 vacation days per year plus paid holidays, 11 sick days per year, up to 3% matching on 401k, pension opt-in after 3 years, weekly telework day after 1 year (you get to pick your day), education reimbursement, FSA card for doc visits/prescriptions, moderate salaries, plus organizational bonuses based on program performance (usually bonus is about $1,000, which is quite low for the area).
Diverse team with a variety of employees - some who have been around a year or less and some who have been here 15+ years.
New management is bringing the organization to a new level and treating employees better and bringing up morale. There is an organizational focus on transparency, accountability, and mutual respect.
All staff except management are union members (OPEIU Local 2) so that comes with a lot of benefits itself.
Relatively laid back environment and you get to pick between 8-4, 9-5, or 10-6 work shifts (also the work week is only 35 hours per week).
Occasional paid lunches, staff birthday parties, and a few annual staff events/parties.
Cons
The salaries could be higher, they are below average for the DC area (but above average nationally). There is a SIX MONTH probationary period which is pretty harsh because employees are not allowed to use vacation or sick time at all during this period.
Currently the organization does not give out cost of living raises each year, so after several years you might have to find a new job if you aren't lucky enough to get a performance-based raise or promotion.
