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?
Context/Details:
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.
Research:
"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).
