<prompt> Human: Hi personal finance,My employer just moved from a 24-week pay period to a 26-week pay period starting this January. To help with the transition, we are getting an advance pay in addition to the two bi-weekly checks well be getting for the month. This advance pay has to be returned to the employer when we end our employment. For me, this amounts to a little above 1000.The way I look at this advance pay is that this money doesnt belong to me, so I dont want to spend it only to end up not having it on hand should I leave my employer and end up in big trouble. So Id like to ask you, personal finance, on what I can do with this extra cash. I was thinking of investing it, but Im not quite sure where to start.A little about me: I graduated college with zero debt thanks to a scholarship and am currently only paying transportation costs to work 25 of net monthly take-home pay. No bills, no rent living with parents, thinking of starting to give some money as contribution, but that is a separate topic.  <response>: Put it in a high interest bank account and forget about it.
