Its absolutely the hours/ days. They scream student
I'm not sure why people are suggesting approaching term time places like schools/ nurseries. Surely those people are likely working mon-fri and are unlikely to want to add on a weekend job to work everyday? You could probably advertise a summer holiday contract but will likely get more students but possibly some term time staff. Doesn't help with your weekends, half terms etc though
Equally people that tend to work term time, tend to do so deliberately because they need the hours for childcare etc. Its quite competitive! Especially because of the term time nursery hours funding so lots of people even with younger kids want term time.
The reality is that most adults can't sustain their life on only weekend work and holiday work financially
Lots of people in that demographic will tolerate weekend work as part of a larger occasional pattern but not solely. And that's the worst hours for anyone with kids.
I'm in my 30s with kids, couldn't afford to take those hours, if I could I'd be pickier because I'd not want to lose every weekend (when friends/ family are off)
My sister who does work part time does so because of children (like most) so your hours would be the worst of all the options. No seeing kids at the weekend and all the summer holiday stress
My mum is also semi retired but supports my sister with child care
The only person I know as an adult that works solely a weekend job is every other weekend because of custody arrangements but wouldn't go for the term time
Is it every weekend working? Full days? Either way is tricky. Everyother is more family friendly/ attractive but less to live off.
5 hours on a Saturday is bugger all wage to live one, split hours across the days buggers up your weekend for minimal pay, Working full days on both Saturday and a Sunday rules out a big group
Changing the way you advertise might change the demographic but I think you'd be lucky and it's not guaranteed
I think you'd be better off improving your training so you can retain, and make the applicants you are getting better
