I am a Blood bank Supervisor and have 35 years of Bench Experience. I do help on the bench when I am not writing procedures, doing Inspections, making up Competencies, Reviewing and scheduling all QC including Activations, Calibrations etc... If you would like to change places with me I would be more than happy to sit on the bench and type results into the computer. i am capable of doing ALL Blood bank work on the bench and also all Supervisor work. If it wasn't for us Supervisors you would not only be doing bench work but paper work, making schedules, writing procedures and doing inspections. Think you can handle all that?!!!!!!!! Also do you think you know enough about Blood bank Standards to be reviewing your co-workers work? If so more power to you. PS Supervisors work more than 40 hours/week and are not entitled to overtime!!!!!!!!
