If someone sends you money by mistake it is not yours and you should return it (the easiest way to do that is to call your bank and ask them to revert the transaction[1]). If you do not return it then it is theft and you may be prosecuted. If a company accidentally sends another company money then things are usually resolved quickly and professionally with a phone call. If a company accidentally sends lots of people small amounts of money then the loss is balanced against the cost of getting it back by contacting all the people and likely some will be returned and some will be stolen. If the accidental transfer is really accidental pay then undoing will be complicated/impossible so if the amount is small enough maybe just pay less the following month (if it’s allowed by minimum wage laws?) and write off people who quit before the company is made whole, though this can be complicated if the error happens towards the end of the tax year or because of taxes that are assessed e.g. monthly instead of annually. [1] there’s a common scam that goes roughly like: 1. Someone sends you ‘too much’ money. 2. They ask you to return the money minus some goodwill payment. 3. They clawback their initial transfer but you can’t claw yours back. So that’s why trying to get the original transfer cancelled is better than trying to return or partially return funds manually.
