Benefits can be expensive, and they only pay you for the 40 hours because it’s a salaried rather than hourly position. They just want free labor at the expense of the employees’ sanity.

Owning a home or otherwise having stable housing doesn’t mean you don’t have or can’t develop debilitating mental health or drug issues. I’ve worked with many currently and previously high-functioning, well paid, housed individuals who have developed severe mental health or drug problems despite their economic security. Economic security and stable housing absolutely are protective factors which reduce the risk of developing such problems, but they don’t eliminate genetic factors, trauma, unexpected economic hardships, etc.

Wiktionary suggests both “fixing to” and “fitting to” are used synonymously. Fwiw, in Tennessee, I only ever hear “fixing to”. As someone who learned English outside of the southern US, it makes little sense to me also. But what makes even less sense to me is people saying “trying to” to mean “want to”.
