When an AE does contain a category displacement, then you can be kicked out of the category against your will.
What about being booted out of base? Say a jr SEA ER FO has no Issue with switching to 737 or A220 in SEA because location is the priority. Any guarantees the jr FO won’t have to relocate base? Does that make sense? Base- important, jet- not so much.
