If your employment is suddenly terminated due to performance issues, especially after your probation period, it's important to understand your rights. The advice suggests not signing a voluntary resignation letter, as this can negatively impact your profile. Instead, let the employer proceed with termination. While legal action might be possible, it's often lengthy and costly, especially given current circumstances. Your immediate priority should be finding a new job, but don't forget to pursue any outstanding dues or final settlements from your previous employer.
