A better way to verify employment is to look for a regular direct deposit through bank statement. This way, you will not only know who is the employer, but also the income and pay frequency.
If you are worried about fake bank statement, you should consider use an electronic bank statement service such as Tenantify (https://tenantiy.com). I am the founder of the company, so I am a bit biased. But we did help landlord solve a major pain point in verifying employment and income.
