员 = 口 + 贝 : Yu the Great and a crab are having dinner just inside the anthill's kitchen. They ordered mandarins, and the waiter serves them.

工 = 二 + 丨 : Mnemonic symbol: a steel beam, since 工 looks like the cross section of a steel beam.

Gitta Giraffe (gu) is working a shift in front of the engine ((e)ng1). Her job is to melt dinosaur bones (丨) so that they can be disposed off easily.
