I had taken a sabbatical of 2 1/2 years due to medical reasons. I resumed work after full recovery. on my return, I am being treated differently by my coworkers and managers, who think I am still unfit. I’m not given key assignments. And whenever some crucial work comes my way, it is on sympathetic grounds. Even if they involve me in certain activities, it’s merely a formality. I feel very isolated. What should I do to ensure my career get a boost and I am treated equally at the workplace?
