I am the only web guy in our firm and get asked to work on client issues even while on vacation (PTO). It's understandable if it's an emergency production issue, but even for non-production/test environment-related issues, when clients reach out, I get called or emailed to address the concern by one inconsiderate coworker.
It's a very small company, so 'To make the customer happy' policy is followed.
How should I handle this situation? Is this scenario common in the industry or should I be drawing boundaries on when I will be available while on PTO with the coworker?
