Oh dear. This has clearly gotten out of hand.
Management has been notified of the goings on amongst the employees.
If you're experiencing any symptoms you fear may cause long term damage, may affect your ability to work or are simply causing you any significant concern, I'll be in the medical tent for the duration of the day to provide evaluations based on our best understanding of the situation. Beyond that, please be gentle with yourself and try to avoid any significant or unusual strains and stresses.
