I wouldn't call the full-time status as "job security". It's healthier to arrange your life and finances in a way that assumes your job can end at any moment. Employers love FT because you pay a fixed salary but you can squeeze more hours out of the employees. This person is case in point. Did she get a bonus? No. She got shit-canned.

There was a study that claimed losing a job caused the same level of grief for some as losing a loved one. Don't be that person. You are just a mercenary on contract, you are not part of a mission, or saving the world or (ugh), a FAMILY.
