you can follow your sims to their work but you can't actually go in the building with them and watch them work.
press on your sim tracker button and then the briefcase will light up when the sim needs to go to work, just make sure they actually have a job first
u go to any work bench, click on the clothes option, and there u go
You can't follow Sims to school or work.
if you mean you want to play as them when they are at work, you can not. you can't go to work with your sims. if you have a business on a different lot then you have to have your sims go to that lot when they are controllable (i.e. not at work)
No, but in the sims 3 ambitions, if you are a stylist or a fireman you can go inside the work place.
click on the bed and put sleep make sure they can get in easily
If your sims do not go to work, they probably don't like their current job. Try quitting their job and finding a new one that matches their interests more.
Speed up the game
You can buy a store through the phone or computer then when you have your own store, you can employ some people to work there. And if you have one of your sims employed by another one of your sims, that's the only way you can your sims work in a shop.
go to work in a good mood.
My guess is that you can't make your sim to a vampire on the sims 3.
