Do you have dressing room space? Sex workers count as performers so they need dressing room space in addition to a locker.
Oh I figured it out eventually, and accidently. I had to fire someone for stealing, it finally opened up and I could hire or reassign someone.
For those just starting up, this can be a fun game. I like games that you build on, and have some type of game management involved. And it can be addicting.
a few pointers I've learned:
-yeah, like others have said, don't go on a hiring spree right away. A cook and a bartender are enough to get started.
-make sure that one of the first rooms you build is a kitchen. It takes forever to build it, so start early...like day 1 or 2.
-like in real life, treat your employees well and it will pay dividends. Go to employee policies and make sure they have days off. Mine is set at 2 days off, at their choosing. It makes a huge difference. Go to your manage club/employees section and look at their happiness. Unhappy employees constantly whine and ask for raises. Also be sure to move around the club and click the "recognise good work" button.
-within a week of opening, check the prices on your drinks..and later meals. Increase incrementally...a dollar at a time to begin with.
-if you are looking to change someone's sexual preferences, you can normally do it when their fondness for you is around 50-60.
I should have mentioned this early, but when you start, run down your MC attributes. Some you can change when you start, others you cant. Endurance and strength are biggies. If not, you spend all of your time in the gym. IF needed, restart the game fresh. You'll save a great deal of time.
Have fun. it can be a fun game. (BUt needs threesome scenes, lol.
