A member of staff is under pressure as he is taking on double of his contractual hours due to staff shortage and not been paid for the extra hours he is doing. He is struggling with preparing lessons and he recently lost his temper with a student and left the class unattended. While the class was unattended a student was found smoking in proximity of flammable material.
When the member of staff was approached and asked about the above he said that he was too stressed because he is working too much and because he has personal problems
