thanks for the link, I read that pdf already three times

it seems to me that HO is worried about the 180 days limit but my once-a-month weekend trip will never come close to that 180 days absence. One confusing that part is the evidence to provide. I can keep all of my payslips for 5 years and send it to them upon application but is that suffificent...The confusing part is this: "There is no specified evidence for this, butyou would normally expect to see:"
So if I don't submit any evidence it is still ok? and it doesn't tell if it is "and" or "or" of the two things. If it is "or", I can just submit the payslips and be done about it but if it is "and", I have to have that annoying list approved by employer....
