Increased micromanagement from your manager may signal a lack of trust and an attempt to create a demotivating work environment.
A lack of enthusiasm or concrete plans for career progression indicates that your employer may not see a long-term growth path for you within the company.
Exclusion from important meetings, key projects, or internal stakeholders suggests that your employer is no longer investing in positioning you as a critical team member.
Sudden, unrealistic increases in workload may undermine your confidence and lead to burnout, potentially encouraging you to quit.
