“お疲れ様でした” (otsukaresama deshita) is the formal version of this phrase, while “お疲れ様” (otsukaresama) is the informal version. If you’re pretty tight with the co-workers you’re saying “bye” to, feel free to just say “お疲れ様” (otsukaresama).

There’s a lot of misinformation out there about “さようなら” (sayounara) being the standard goodbye greeting. This definitely isn’t true—in fact, you’ll probably get some strange looks if you say “sayounara” to a native Japanese speaker.
