^not necessarily. kasi the DOLE explained that section in the Q&A kasi nga vague yung "only occasionally or sporadically and not on an occupational basis". so prior to the release of the Q&A, iniisip natin na pag twice a week or once a week lang si lavandera, baka hindi nga siya covered kasi "occasional" lang. pero the law did not define what is occasional. so we can't just assume that once a week is occasional or twice a week is occasional. and actually, even "once a week" is considered regular because there is a regular schedule. nevertheless, that doesn't matter given the explanation below.
that's why the DOLE clarified the phrase "only occasionally or sporadically AND not on an occupational basis". the emphasis is on the "and", hindi siya "or", so hindi lang basta occasional pero dapat "not on an occupational basis" din. that's why the examples given by DOLE are as follows:
"4. What are the examples of persons performing work occasionally or sporadically and not on an occupational basis?
a. A janitress doing irregular laundry work for a household during rest day;
b. A construction worker doing casual gardening job for a household; or
c. A hospital nurse, or a student, doing baby-sitting job."
- so based on DOLE's clarification, the phrase "any person who performs domestic work only occasionally or sporadically and not on an occupational basis" means that hindi yun yung primary occupation nila, like in the examples janitress, construction worker etc na suma-sideline lang ng domestic work pero that is not their main occupation. si construction worker hindi gardening ang occupation niya kundi construction work. that's what that phrase means.
kaya ang lavandera na "twice a week" or whatever ay may risk na ma-cover nung law. but as i said before, the RA itself nor DOLE's Q&A has not yet addressed that specific situation na paano kung "more than one" ang amo na pinaglalabhan nung lavandera. let's check if there's a hotline that we can call to ask these specific questions.
