Tiger Woods has garnered some harsh criticism from someone he used to work with.

Lindsey Vonn Continues To Live Her Life Amid Breakup With Tiger Woods

On Sunday, Sporting News shared the details from Woods' former caddie Steve Williams who split from the golfer in 2011. It seems that Woods' behavior would go on and off, and Williams felt like a "slave."

"I was adamant that some of his behavior on the course had to change," Williams wrote in a book. "We was well known for his bad temper and, while that wasn't pleasant to witness, you could live with it because it ended as quickly as it started. But he had other bad habits that upset me. I wanted him to prove to me he could change his behavior and show me and the game of golf more respect."

This gives some implication on Woods' breakup last May with Olympic skier Lindsey Vonn. A lot wasn't mentioned on why it didn't work out for these two, but based on the caddie's words, perhaps there could've been some hostile tension.

Williams also gave specifics on what the pro golfer allegedly did when they were working together.

"He would flippantly toss a club in the general direction of the bag, expecting me to go over and pick it up," Williams wrote. "I felt uneasy about bending down to pick up his discarded club, it was like I was his slave. The other thing that disgusted me was his habit of spitting at the hole if he missed a putt."
