2 jobs for spouse visa

[photoman48]

Hi everyone, I’m really new on this forum and I’m finding it really helpful. My wife will be my sponsor. She finally found the second job. Her main is on salary, she earns £16000 yearly. Her second job is zero hour contract. She will get paid 15th of every month so she will get paid 15th January for her main job.(£1.333 every month) She just started on her second job, Her second job will pay her every two weeks on Thursdays. So she will get paid on 24th of January and 7th if February, she will do minimum 18 hours (£144) each payslip. So totally she will work 36 hours in a month. We really wonder does it matter if she doesn’t meet totally £1550 with 2 payslips in the same month? Or is it gonna be okay if she earns £1.333 6 months (6 pay slips from her main job) + £144 every two weeks (13 pay slips from her second job)
She just doesn’t meet £1550 in January (this month) so she can meet £9300 in 6 month. As I sah we confuse about not meeting £1.550 in January, other months are fine we think.
Thank you very much for help!
