BAKERSFIELD, Calif. -- A former driver at a local delivery company called the Eyewitness News Tipline saying she's owed hundreds of dollars.

Kathy Wesley was hired as a driver for delivery company Velocity Express in April. "In the beginning it wasn't bad," said Wesley. "I enjoyed working there."

However, she said that feeling quickly changed in July.

"To me it felt like a prison. Go from 5:00 in the morning till 9:00 at night," she recalled. "Go to sleep, do it again the next morning."

But it wasn't just the hours that got to her, Wesley said her paychecks didn't reflect the work she had done. "There was stops in there they hadn't paid me for," she said. "I thought okay let me check the rest of my paychecks."

When Wesley went over her past checks she realized that the unpaid stops happened every week.

Wesley then went to her supervisors, but nothing was resolved. "Never did see that money," she said. "(The) next week, I got my paycheck (and the money) still wasn't there and more was missing, so (the debt) accumulated."

Wesley believes she's owed over $1,100 and said many other drivers are also owed lots of money.

Eyewitness News called some of those drivers, and found they had similar stories to Wesley. Some said they were shorted money on their checks like Wesley, others claimed they were promised a flat rate for their work, but were paid differently. Some of the drivers said they are owed anywhere from $1,500 to $3,000.

And it wasn't just drivers who said there were problems, former supervisors and managers agreed.

One former supervisor, who wanted to remain anonymous, confirmed that many drivers' paychecks would be short $100 to $200 every week. "A lot of them didn't even have enough money to pay for gas at the end of the week," said our tipster.

Velocity's former City Manager, Brian Estrada, was laid off in June and said, "The operation itself was being run pretty bad, in my view."

Estrada said the checks would be manipulated. He claimed that Velocity had a targeted amount they wanted the employees to get paid, and if an employee got paid more, then the employee's pay would be lowered later on to meet that set amount.

While there is a local office, Velocity is headquartered in Connecticut. Eyewitness News contacted them about the employees who claim they haven't been paid properly.

Velocity's Executive Vice President of Workforce Resources, Kay Durbin, said she wasn't aware of the discrepancies and later released this statement: "Velocity management is researching this matter and attempting to contact each of these individuals to further research and resolve any pay discrepancies or errors."

While Velocity has said they will investigate our tipsters complaints, the former and current employees that Eyewitness News has spoken with say the problem is at the local office.

"It's the upper management," said the anonymous former supervisor. "They're just looking to make their money."
