I'm currently navigating a tough decision about potentially rejoining my previous company after leaving during a Performance Improvement Plan (PIP) due to medical reasons. I had been with the company for 4.5 years and was performing well until my health issues impacted my work, leading to my placement on the PIP. Unfortunately, the situation became overwhelming, and I resigned shortly after, which was a difficult choice. My medical condition, which has lasted over two years, was known to my manager and HR, and everything was well-documented. I'm still in recovery and expect it to take another 2-3 months. I've been considering whether it's worth trying to return to the company once I'm fully healed. My former manager mentioned that he would let me know if there’s a vacancy when I'm ready, but I’m unsure if he was genuinely sincere or just being polite. I'm looking for advice from anyone who has been in a similar situation—how is rejoining after leaving during a PIP viewed internally? Should I pursue this opportunity or focus on moving forward?
