Answer:
The correct answer to the following question will be "immediate supervisor".
Step-by-step explanation:
- The "immediate supervisor" seems to be the manager or supervisor who has already been appointed by both the sector to empathize with such a negative comment from workers during their working area, as well as to accept written complaints and operation them to either the correct stage throughout the technique or procedure.
- The very first "open window" is perhaps one of the individual worker's immediate supervisors, founded on the principle that both parties in dispute will first try and find a resolution collectively.
Thus the above is the right answer.
