If you hire employees or take on volunteer workers you are likely conducting background checks through a background check company. Not every background check company is equal and there are considerations to be made.
How easy is it to do business with them? Are there any human beings who can intelligently answer questions available? Do they offer online services? Are the services easy to use?
What types of searches do they do? Not all background checks are the same. There are multiple areas to search in a criminal background check and it is not difficult to miss an issue with criminal history. Do they offer a credit history check? If your candidate will be handling money or valuable inventory you want to be sure they are creditworthy/ responsible.
Where do they look? Again there are multiple databases out there that may contain information you need and going with a budget priced background check company will likely mean they are doing a minimal/ surface search and not digging into detail.
Are they looking at workers compensation claims? There are people out there who “work the system” costing employers small fortunes in high monthly insurance costs due to false claims.
What is the company’s background? New companies pop up every day because someone has a get rich quick idea. Look for well established companies with a positive track record.
