So the scenario is like we and another company are working on a common project. I often visit their office for discussion and meetings. For the first few months, it goes very well. After that they started to call me after office hours and even on weekends.
This was for discussion the software development cycle and other things in project without notifying my team members.
I don't know what to do. My onsite is regularly calling me after office hours and they want me to discuss the next page phases of the project. Sometimes they want me their in team discussion on weekends without informing my team members or my immediate boss
I never answer their calls after office hours, is this ethical?
Note: There is no such deal to offer extra pay during extra hours working or working in weekends. I don't know what agreement was signed between them. They even refused to clear the RFP
