For passing probation in my new job I was expecting a 500 quid salary boost.

For Decembers pay I got significantly more than expected. I messed about with a salary calculator for a bit and based on the numbers it would appear that I got a 3k increase.

I'm not entirely sure what to do about this. I mean, if it's genuine, I'm obviously delighted, but I'm thinking, what if it's a test of honesty?

The way I see it, I have three choices..

One is to leave it until next month and see if I get the same amount, then I'll query with the COO.

Two is to query it right away as soon as we start back on the 4th.

Three is to just say absolutely nothing at all.

There was no mention of any extra Christmas bonus going to be added to our pay. But even so, the numbers are very specific and would work out at exactly 3k.

What would any of you fine fuckers do?
