The phrase comes from a long list of instructions, dos and dont's with a medical context. However, I'm afraid that I don't have any other information whatsoever; just the instructions and a general medical context.
Erklärung: Possibly, 'balance of shift' means the balance of hours of a shift which are not worked. There is an 8 hour shift. An employee works for 3 hours. The shift supervisor then sends the employee home, or the employee is taken ill, or injured. The balance of shift would be the 5 hours, for example because of illness or injury.
Erklärung: This would make sense in a context of dos and don'ts where you get the instruction not to shift your balance while handling something sensitive. I can see this in a surgery environment.
Just a guess, though!
