I think this is mostly a US thing. Why use yearly salary? You’re not paid once a year, are you? Most likely once a month. Referencing monthly salary makes much more sense.
“I’m making 50k”. Great, now I have to guess - dollars? Monthly? Yearly? If yearly then what’s the monthly paycheck? Net? Gross?
My bad, I didn’t get notified someone replied to my comment and only just checked. As mentioned below in this thread, I meant we get 14 monthly salary payments, where “months” 13 and 14 are less taxed and are tacked onto a summer and winter month as a holiday and christmas bonus, respectively.
