If only we lived in a perfect world, you could just add another cubical to your cramped office space. It could extend out the window and make a little protruding chunk hanging over the sidewalk. But, in real life you can’t do that unless you own an R.V. with a living room that extends outward (actually very affordable.)
Moving your office to another location so that you can accommodate that 9th worker could cost thousands and might be a decision you need to reverse later on. Squeezing that 9th guy in might be very uncomfortable as well. It might be better to create a virtual office by outsourcing. You can get virtual help in countries all around the world these days. There are also freelancers right here in the USA who can work from home. That way you get labor when you need it, but don’t have to commit to office space.
Shared offices are another alternative. You might have your main office in one location, but a few blocks away rent a room or two in a shared office. That way, you know where your people are, and don’t have to commit to a two year commercial lease!
Virtual assistants are a popular type of person to outsource to. Most call centers can give you someone to do phone work for you. Many will let you lease an employee for as little as eight hours a week! Imagine if you only need half an employee, rather than sawing them in half, just hire a virtual assistant in Makati City, and you have it made!
