Manager here, they will have an impact on future assignments for 2-3 years depending on how you respond and recover. If you recover the next year, you’ll be given credit for fighting through it, and after 2 years, you should be mostly fully recovered. Some harda$$ managers might not want you after 2 years, but most won’t have access to that data. After 3 years, you shouldn’t see any issues. Salary treatments will be impacted (0%) for the next year, but can come up the following year if you get out of NSI.
