Using Service without Effect.all

is there a way to use a single service without using effect.all ?

i.e

pipe(
///some effects before this,
Effect.all([JobService]),
Effect.flatMap((jobService) => //use service here)
)

pipe(
///some effects before this,
Effect.all([JobService]),
Effect.flatMap((jobService) => //use service here)
)
