I'm hoping for some help in dealing with a scrum master who is directly going against the wishes of the development team.
The scrum master in question has an approach which puts completion of sprint stories above essentially everything else.
Generally, a developer (person A) might hit a bit of a road block and request assistance from a member (person B) of another, more experienced team. It should be noted that the latter team is a remote team working in a timezone 5 hours behind, so delays are expected, and sometimes issues can take a day or two to be resolved regardless.
What has started to happen is that even if the developer states that they're in control of the situation, the scrum master will email B, or sometimes email B's manager, stating that A is blocked and needs immediate assistance.
The development team brought this up at the last sprint retrospective, and the scrum master reluctantly agreed to stop unless assistance was directly requested by a developer.
The developers' concerns were that the scrum master was driving a wedge between the two teams and that his emails would lead to animosity between the teams, as it could be interpreted that the developer sanctioned the email.
Although agreeing to stop, the scrum master has continued to send these emails.
How could this be dealt with in a professional way, with the goal of making this stop for good?
