This is beginning to look like spam. But, I will answer anyway.
It doesn't matter how well your bosses know you. Only resort guests may use the pools and hot tubs at any WDW resort. As a CM, if you are caught, you will be reported to your department supervisor and you will get a repremand or dismissal.
If you would like to use the pool at WL, you can use your CM discount and book a room. Then you will be considered a guest at the WL. Keep in mind, as a CM, you are always representing the company no matter if you are on the clock or not.
