Staffing rates as mentioned here may seem average. I found in recent years that CNA's, STNA's, or Nursing Asst's would get assignments until 30" into shift one is pulled without communication. You mentioned Unit Secretary pulled frequently and Restorative, Risk Mgmt, and other Resident Care functions cut. All these factors lead to burnout and reduced work-life balance. The best way of furthering education may be a Master's Degree to be successful and satisfied by your career. Best wishes with a suitable study track in your future!
