West Bengal Services Rules 1979

The rules for government employees to keep their job positions, called "lien," allow retaining the job and its benefits. Lien can be lost when taking a new job, working in a different cadre, or transferring abroad, then regained when returning within three years. "One time confirmation and lien" means confirmation happens only once at entry post when meeting requirements. Confirmation is no longer tied to permanent job availability, and if too many people have lien, junior employees may be reverted to lower positions.
