Hi. My boyfriend recently put in for 1 day off on vacation. The request was rejected and he was told they were too busy to allow him to go on vacation. When they informed him of this he asked if he could cash out his vacation hours since he would not be able to take a vacation this year. They told him he was not allowed to do this. Every company that I work for has allowed this. He has not maxed out his hours yet and is not losing them yet. Is this legal in the state of California?
