I never recommend that anyone resign. You never know what rights you are giving up. For example, if you recuperate within one year of termination, you can request to return to work. You need to speak to your union before deciding what you should do.
Resignation will likely impair your ability to receive unemployment benefits, but this may not impact you if you are out on disability or workers' compensation.

A CSL § 71 provides the occupationally disabled employee is entitled to a cumulative leave of absence of at least one year, and the employer may extend a Section 71 leave beyond a year, but is not required to do so, and you should consult a labor law attorney before you decide to do so.
