The first thing that you should do is, make sure that you have enough staff. No matter what your business or what you are doing, having an office that is permanently understaffed is a poor idea. Understaffed offices are ones where people are going to be doing more than their fair share of work, and it is going to make the employees resentful. They may put up with it for some time, if you can honestly explain it away as something that is temporary and will not be repeated, but eventually they are going to start looking for other jobs. Take some time and make sure that you have enough people for the work that is coming in.
Another thing that you will want to do to keep your staff from exploding is, treating them with respect. Many executives tend to treat their employees like tools or like people who are not worth talking to. If there is no respect between the ranks, you can be sure that you are setting up an us-and-them mentality. This sort of disdain is not helpful for any office; you will soon realize that when you are thinking about making the office hang together, it is your enemy. Take some time to get to know your employees and to really think about how you are going to treat them; the more invested they feel in the company, the better off you are going to be.
Remember that rewarding your staff for a job well done is quite important. There are companies that reward their employees, but then they do it with things that no one wants. On the other hand, remember that when you want to reward someone, time is always a good option. Giving your staff the option to go home early or to take more vacation days are definitely things that they will look on with appreciation. Also, remember that the more flexible you are, the better you can be for them in general. An office that allows their employees to get the results that they need and which will support them through being flexible with their duties is something that can make a huge difference.
Take a moment to consider how you can keep your staff from exploding; there are so many important choices for you to make, so think carefully!
