Työpaikassaan

Työpaikassaan is a Finnish adverbial form meaning "at/in his, her, its or their workplace". It combines the noun työpaikka ("workplace") with the inessive case marker -ssa (indicating "in/inside") and the third-person possessive suffix -nsa/-nsä, giving a sense of belonging or relation to a person or group.

Grammatically, the sequence is: työpaikka → työpaikassa (in the workplace) → työpaikassaan (in his/her/their workplace). The possessive suffix -nsa/-nsä is neutral with respect to number and can refer to singular or plural antecedents; context clarifies whether it means "his/her" or "their".

Usage is common in sentences describing location, feelings, conditions or actions relating to a person's workplace. Example: Hän viihtyy työpaikassaan (He/she enjoys being at his/her workplace). Without the possessive suffix, työpaikassaan contrasts with työpaikassa (in the workplace, no explicit possessor) and työpaikallaan (at his/her workplace using the adessive locative), the latter carrying a slightly different spatial nuance.

As a standard, neutral expression, työpaikassaan appears in both spoken and written Finnish, including news, official texts and everyday conversation. Related forms include työpaikallaan, työpaikoissaan (plural possessive), and työpaikoissa (plural inessive without possessive).
