<p>The correct answer is (B) employment.</p>
<p>In this sentence, the phrase "regular ______" is describing what the workers are seeking. Since the phrase is referring to a noun, we need to choose a noun form to complete the sentence correctly.</p>
<p>(A) employee is incorrect because it is a noun referring to an individual who works for someone else.</p>
<p>(B) employment is correct because it is a noun referring to the state of being employed or having a job.</p>
<p>(C) employing is incorrect because it is a verb form, and we need a noun in this context.</p>
<p>(D) employers is incorrect because it is a noun referring to the individuals or companies who hire employees, not the state of being employed.</p>
