They grossly under pay their employees - Anonymous employee CSL Plasma Employee Review

pay, easy work, plenty of room to advance

can be stressful depending on staffing and donor flow

I made a lot of friends there, and the employees on the floor were almost always very hard workers

The higher up in leadership you go the less you actually seem to care for the people actually doing the hardest work on the floor. The donors are often mean and impatient. And don't get kicked out if they are repeatedly an issue on the floor, because that's a loss of plasma. Many centers won't kick out anyone with veins that aren't suitable to be stuck. It's often up to the donor to walk out with two blown veins to decide not to come back.
