The other half just started a new job and when pay day came around she'd been paid for two weeks instead of the one she worked. (I am under the impression the you get paid in arrears, not in advance).
Any way, I said to mention it to the boss just to keep things above board, and he said it was ok and not to worry about it.
Have you ever been over paid? What did you do about it?
I've never been overpaid, but whenever I 'hear' (usually from Chinese whispers) of people getting over paid, the boss/money handling people find out, and the money is paid back.
I guess if the boss okays it, it is all good.
Maybe it is their 'honesty' detector, and the misses has just passed it by letting the boss know.
That was the first thing that popped into my head too. Apart from that, the boss is pretty impressed with her knowledge in the industry which may have something to do with it.
Waaay back fifteen years ago I got paid double one month so I just stuck it in a savings account and picked up the interest. Four months later, payroll realised they'd double-paid and asked me about it...I feigned any knowledge of it and said I'd have to check my bank statements. A few days later I said "Oh, you were right. I hadn't noticed. Here's a cheque for the amount you overpaid me."
Never heard another word about it. Payroll were probably relieved to have fixed their stuff-up without a drama.
A shame it wasn't enough to retire to Maui, otherwise I doubt they'd have found me! 
I think I have worked in a company where they paid you one week or two weeks in advance. I can't remember why, except for the disappointment when you leave and realise that you have already been paid for the work you have done.
I think it was an arrangement where they paid once a month, and just did it this way.
A couple of years ago I was double paid because of a stuff up by my employer's bank, Westpac. Everyone was double paid and so were employees from many other companies using Westpac for their payroll.
Unfortunately the overpayment was pulled out a few days later. If I was smart I would chucked it off my mortgate and then agreed to pay a nominal amount say $100 a week off till the overpayment was paid back. Unfortunately I'm not smart.
Maybe she only told you she was getting half the pay so she could spend the difference on herself and you caught her out? 
Many years ago my first job was part time night fill at a major supermarket (starting with W). The night fill boss would (illegally) sign our time sheets instead of getting us to sign them. (we were all teenagers at the time and didn't know our rights). The boss would always sign us off early, ie at 11pm would announce, "you are all signed off for 11:30", this would be done with the full knowledge that there was no way we could finish by that time. We would work our butts off for the next hour plus and be underpaid for our efforts.
After many months of regular work I took a week off (unpaid).
It seems they continued to sign my time sheets while I was away.
The following week one of the bosses said to me, "don't you want your pay?" For once in my life my brain was faster than my mouth and I replied, "didn't I pick it up?" (these were the days of cash payments, folding stuff & coins).
He handed me the pay packet and then went through the entire store, telling all the staff what an idiot I was because I didn't pick up my pay and had forgotten it.
I quitely worked away, happy that some of the unpaid extra hours had now been paid.... 
i got paid a contract twice, and i hadnt picked it up till the end of the week and when i mentioned it the other company got all ****ty with me for not telling them sooner
It might be paid fortnightly, one week in arrears and one week in advance.
See what's paid next time and it might all become clear.... as mud.
I get paid two weeks in advance and two weeks in arrears.
(Get paid on the 16th of evey month)
Companies like to do as it naturally saves the business resources.
It also makes less work when it comes to accrueing for payroll liabilities (as they wont exist if your on salary)
The bad news is getting paid once a month....
I find it strange that anyone would want to pay someone in advance for something they haven't done. If a person was to do a runner, then the company would be out of pocket.
