It's all contract work with no benefits unless it's a long contract, so Unicef saves money. Year round job opportunities don't exist unless you're living in the city where the main national HQ is. Even supervisors are hired on contracts so there's always this crazy learning curve where everyone adjusts to new staff frequently due to new staff coming on board and "old" (meaning more than 3 months) staff leaving as their contracts end. As a result, training can be sub-par depending on the manager. Screw ups on paycheques are normal, and you're not compensated for using your cell phone to do company business outside office hours, and getting overtime pay is as tough as scaling Mt. Everest without a Sherpa guide. Don't count on a job reference after your contract is up, as most likely your manager will be gone too as his or her contract ends, or you may have worked with 3 supervisors in 3 months. Work hours can be sporadic depending on the department's budget.
