For specific labor laws you need to contact your States labor board or (L I). Once you have read the governing laws for vacation and time off etc. you will be able to copy some of that language for your memo.
legal. banks and similar instituions can and do demand that their employees take vacation and prohibit entry onto the premises during said vacations. the intent of this to deny acess to computers and so forth to anyone trying to commit ongoing fraud or embezzlement.schemes often break down if the employee is not able to come to work to keep the books cooked
I ve never heard of anyone expecting to get vacation time, if they didn t take vacation days... except for if they no longer work at the place. Yes it s legal to not pay people for vacation pay if they were working that day, otherwise they d be earning twice their regular pay.
