A negative inventory balance however is a much different thing. It's always quite unnerving when you're looking at your inventory from your office computer, and see something like -75 boxes of lettuce. You often wonder what you're going to see when you go back there. Will there be a black hole in the pallet leading to another dimension? The sky is the limit when it comes to these things, but chances are there are one or two things causing your negative inventory situation.
The first possibility, as many in operations manager jobs know, is the issue of timing. In a warehouse there are often many pallets of product going in and out of the warehouse at a time, and it's possible that someone took product out of an area that just wasn't stocked yet. Yes, it sounds like a pain, and it usually is, but fortunately this isn't a severe form of negative energy, as most of those in operations manager jobs know. Usually all you have to do is, wait and the problem will resolve itself nicely as the inventory is restocked and the numbers return to the positive.
Then you have the other occurrence of negative inventory, which those in operations careers really do not look forward to. These occur when someone accidentally reported taking more from an area than was actually there. For instance, let's say you have 500 boxes of product in one location, but you have 50 in another location. If a person takes 500 from the location that had 50, then the number of boxes reported there would go to -450. This causes some severe issues in the inventory system that you're going to need to take care of right away.
Because the second example is not a mere timing issue, you're going to find that it takes much longer to fix. You don't want to simply correct the numbers, you need to go to the locations, check paperwork, talk to people, and determine where the mistake actually occurred. Operations manager jobs can be tricky, and this is one part of the job that is very time consuming, but in spite of that it's a very rewarding job, you get to make a difference, and you'll feel great about your accomplishments.
If you are wanting to get into operations manager jobs, then you will need to write yourself a decent resume. Write down your level of experience, what you are good at, anything that would be relevant to this job. Make sure however that you do not exceed one page, as most employers will lose interest after the first page. If you are in doubt, employ the services of a professional resume writer, as such a person will no doubt help you into the operations careers you've always dreamed of.
