This is a word- or phrase-request question.
Question: What is the pair of adjectives that best describe
- a [consistent/regular] weekly earnings pattern and
- an [inconsistent/irregular] weekly earnings pattern?
There are two unemployed workers:
Worker A earned $500 every week prior to layoff.
Worker B had varying weekly earnings (e.g., week1=$500, week2=$350, week3=$0, week4=$700). This person can be a construction worker, a painter, fisherman, plumber, part-time casual worker, or a freelancer, etc.
In the following sentences, which I wrote, I need the appropriate word to go inside the square brackets.
(Worker A) An unemployed worker who had [regular?] weekly earnings prior to layoff gets the same amount of weekly benefits across all regions, regardless of the regional unemployment rate.
(Worker B) In contrast, an unemployed worker who had [irregular?] weekly earnings prior to layoff will receive higher weekly benefit payments in high unemployment regions and lower weekly benefit payments in low unemployment regions.
"Inconsistent" does not work. The definition below does not mention that term "quantity" anywhere, which makes me think that it cannot be used to describe the variability of "money/earnings".
If a reason, idea, opinion, etc. is inconsistent, different parts of it do not agree, or it does not agree with something else; not staying the same in behaviour or quality (Cambridge).
"Irregular" does not work for the same reason; it doesn't include "quantity".
(of behaviour or actions) not according to usual rules or what is expected; not regular in shape or form; having parts of different shapes or sizes (Cambridge).
The following terms - "variable weekly earnings, varying weekly earnings, irregular weekly earnings, inconsistent weekly earnings" - returns nothing in Ngram and in Google news (a few hits but not credible).
