My company has 5 trucks that we run. I have three of them that formans take home. I am not really in favor of this practice, but my partner feels strongly that this helps the guys as a "perk". My question is, how do I regulate the use of their gas during off hours. It's almost impossible to check their mileage each day because sometimes I won't even see these guys. Any suggestions or experience in this. I don't like paying the gas bill for them to run around after hours! Thanks!
