Q: I am a software engineer, my core competency is to develop & support software. Now I work for a software company which has projects only from one insurance company. So our company is responsible to make sure all IT related infrastructure is up & running all the time for this insurance company. And my job is to support the software application which the insurance company is using, so if the application has any issues or users of the application need any data/reports/help, I need to help them and make sure they don’t face any issues. Mostly I will be sitting in my company and supporting these applications. So I am not directly working for the insurance company. So my question is if it is permissible to work for this software company?
