Hi
This type of activities is happening in 24/7 environment industries.
You can sent them severe notice to them and also you can give them two or three days (Management decision) suspension memo for the activities. If it is happen first time you can take this action like this since they are affected the production also the productivity time.
"Negligence of work" will be punishable.
