What sort of resistance would youexpect from employees? -

I don t expect any resistance from employees. Why do you?

None. They should be submissive to all requests, especially sexual ones. This is why they are subordinates. Maybe try using a different position request. They may compromise on what sort of toys you wish to use, but generally speaking, the buck stops with the employer. You re paying them, so you own them for the time you are paying. Pretty simple really.
