Pros
Love the environment and great colleagues! You are not forced to be binded by rigid work process. Management is receptive to new ideas/initiatives/solutions. This in turn will force you positively to develop critical thinking, discovering practical solutions and taking smart risks which is a good growth. Being in a small, diversified and closely knit environment, you also get the opportunities to bond well with smart and fun loving colleagues.
Cons
Since most of the employees are either working independently or working on different projects, this would also mean you do not have another colleague to cover your work while you are on long leave. As such, there will be tendencies for you to still be checking and replying to your emails and Skype messages while you are on leave.
