dismission

The act of dismissing or sending away (someone).

Though Mrs Honour was principally attached to her own interest, she was not without some little attachment to Sophia. […] She no sooner therefore heard a piece of news, which she imagined to be of great importance to her mistress, than, quite forgetting the anger which she had conceived two days before, at her unpleasant dismission from Sophia’s presence, she ran hastily to inform her of the news.

Removal from office; termination of employment or services, or position in ones affections.

I told her […] that her dismission was intended for an indignity to me; that I was very sorry to be obliged to part with her, and hoped she would meet with as good a service.

Fairservice looked very blank at this demand, justly considering it as a presage to approaching dismission.

The setting aside (of something) from consideration.
