High hourly pay and paid sick leave.
Because it is a union shop, number of days off are non negotiable and according to a formula. So don't expect to negotiate that during hiring. Also, working from home is almost unheard of. I only know one person who was allowed to for specific reasons and timeframe. Obviously there are no performance bonuses because it's a government job. Best things are very good health benefits. Some departments allow flexible schedules such as starting work earlier or later (# of hours is fixed). There is a govt equivalent of a 401k.
List based on reports from current and former employees. It may not be complete.
