Time to start looking for a new job? [closed]

Current situation (Scrum Master), Senior management:

• hired new hires (Scrum Masters), I am longest serving employee
• 'forgetting' to invite me to important strategic meetings, but not forgetting to invite the other Scrum Masters. At current company Scrum Masters do a lot of agile coaching and are involved with guiding Senior management on how to improve process at team level based on feedback from Scrum Team.
• Replacing me as Scrum Master on a workstream, but reliant on me to do a 'handover' to new Scrum Master who is struggling and not acknowledging he is, or the good work I am doing to help upskill him
• Unlike other Scrum Masters, not taking a lot of my ideas/proposals seriously, reporting etc

I have spoken to Senior Management about their plans for me, their plans are the following:

• To run a new work stream at some point
• To support new Scrum Masters
• To take a step back and let them make strategic decisions which doesn't sit well from their inexperience at commercial level of this org

However, feeling a bit unsettled and undervalued since I feel that I am being deliberately brushed aside, as I am not involved in any strategic decision making without any long term plan being properly established. Feels like I have been stripped off my responsibilities, and I am now a bit anxious that they are setting me up for other people to take credit for any good work I produce. For example, after I upskill Scrum Master struggling.

Do I have any right to be concerned, should I start looking?
