Damage while at work, who's liable?
I work at an automotive repair shop. One of our old employees had an unpaid bill that we turned over to collections; we'll call him Tech A. Tech A is disputing only part of his bill.
Here's the deal:
Tech B had an engine from one of his personal cars on our business's jackstand because he was fixing it after hours. While Tech A was cleaning up the shop one day, he knocked over Tech B's engine. Techs A and B made a verbal agreement that Tech B would get the replacement parts and Tech A would pay to have the repair done, because it had to be subletted out of our shop. This agreement was witnessed by our shop manager.
Now it's a few years later; Tech A says he'll pay for his other parts but not the repair done on Tech B's engine because Tech A is claiming that:
1) our business insurance should have paid for the repair because Tech A was cleaning our shop at the time the accident occurred(talked to my insurance company; aside from this occuring too long ago to even consider filing a claim, my agent said that no, this is not something that falls under the policy because Tech A wasn't working on a customer vehicle, he simply damaged another person's property)
2) Tech A isn't liable because it wasn't his engine(not sure how he can claim this because even though it wasn't his engine, he caused the damage to it)
3) the jackstand was bad and that was why the engine fell over(not true at all; we have used this jackstand on all of our customer's vehicles without any problems; if we had a problem with it, we would have bought a new one)
4) Tech A never agreed to pay for the repair and that we put it on his bill without any authorization(talked to Tech B and my shop manager; both confirmed that Tech A was supposed to pay for any and all repairs to the engine)
So my question is: can I legally force Tech A to pay for the repair to Tech B's engine? Both Tech B and my shop manager are willing to sign affidavits stating what the original agreement was. Is this something that will hold up in small claims?
