Hello all. I hope all is well including your season. I have an important question regarding my employee. He's a great worker, arrives early, never calls out, stays late and never complains. He's my go to guy if I need something and he's dependable. Now here's the catch. A month ago he hooked my landscape trailer to the truck and forgot to latch the coupler. It came off down the road and was dragged about 50 feet. Today, his fifth week using a walk behind with a sulky, he hopped a root and drove the walk behind off of a four foot wall bending a bunch of stuff like the bracket holding the sulky and the hand grips. I told him a number of times that when he approaches "danger areas" such as drop offs from walls, that he needs to step off of the sulky and walk the area as he mows. So, my question is this, what should I do about his carelessness? Should I write him up and document it? Should I ........? What? Please help with ideas as I am not sure what to do. I don't want to fire him and if he quit I would be losing a good worker. This is his third year with me. Is there some sort of paperwork I can copy from you if I do write him up? Thank you in advance for any ideas or opinions you decide to share.
