Plz help! "Job Contract Rule "

[rough_idea]

Hello everyone,
Seeking your expert advice on Uk immigration rules for a salaried employment.
Just a confusion ,can I use category A to meet financial requirement when I have a job on permanent basis ,but this job has such a contract which will be re-new after every 3rd month.( here renewal means negotiation of some conditions but my salary is consistent and completing my requirement )
Does this make any difference when my contract shows a renewal basis after every third month?
kindly guide me in this regards.
I have known about other requirement of 6th months wage slip,p60,bank statements and employee letter .But just a little confuse about the nature of job contract.
Thanks.

Shouldn't be an issue as there are people on temporary contracts to sponsor their partners... as long as you have six months of documentation prior to application I don't think the duration of the contract matters.
