These cons are strictly related to Sales, as I have no experience in other departments here.
This can be a stressful job. Of course read above for how rewarding it is! It requires a high level of consistency in productivity, and in attitude. It's not always easy finding the energy or enthusiasm that are really necessary to do a job like this. We are customer facing, and customer focused, so being low energy and having a bad attitude will make for a very frustrating experience. You have to be prepared to put in the work, even when you don't feel like it, and no one here will actually force you to do that. It is all about self-discipline and self-control as it's a very lax environment. In spite of various reviews on this site, there is very little micromanagement. While that sounds like a pro, it also means that you have to manage yourself, and that is challenging. If you like being challenged, then read all of this as a Pro. If you don't, and you need lots of direction and external input, then read all of this as a Con. I have literally never been told to "Get to work." If you need to be, then this is a BIG con. If you don't need to be, then you'll love it.
It's commission based which is both pro and con. Again, self-discipline and self-control are the key here. If you have both of those, being commission based will be a Pro. If you lack them, it will be a Con.
Hours can be long, and work can follow you home. Phone calls and emails don't automatically stop coming in at 6pm or begin at 9am. Our customers will have issues and needs round the clock, and sometimes across the globe. We are not required to work extra hours, but most of us will at some time or another because it's what's needed to get the job done. Again, if you're looking for a job that begins and stops at a specific time, then this is a con. If you're not, then it's a pro.
