Employers made irregular payments

[Heyall::)]

Hello everyone, hope you're all well & aren't as frustrated as me!

I am hoping to submit my spouse visa application by the end of the month.
I work at an independent business, takeaway to be precise. My employer has no set date or day as shown on my bank statements for payments. No specific day or date that I get paid. They are however, either 4 or 5 payments every month, i get paid weekly. There is no consistency in payments, being either 4 days apart or 10?

Will this be a problem for my application? Will I need to explain anything with my application? I feel my employer has really failed me? Or will a explanation from my employer be enough to clarify this?

Any advice would really be appreciated.

P.s. I am sorry if this question has been asked before. I did search for any topic related but failed to find one. If that is the case, if someone could kindly guide me to the correct page?
