Basically telework technologies directly impact the internal environment of the company. For studying the impact of this technology in a company, through PESTLE analysis, you will start from social analysis, because it directly increases the interaction among the employees. Then economy of the developing countries is also impacted through it. You can study the worth of the company and the economic growth of the company by the comparison of the previous months. Similarly, you can study that how the legal structure of the company has changed, like new laws introduced by the company or the company is shifting from democratic to autocratic structure or not. II have given you an idea and I think you must be able to continue it. Good luck!
