Re: If you are infectious - stay away from work
Bizarrely, and for what most people agree are political reasons, NHS staff in the UK are also strongly pressured to come into work regardless of whether or not they are ill, including with infectious diseases.
Failure to adhere to an entirely arbitrary limit on number of bouts of sick leave results in disciplinary measures then sacking.
If you have to set foot inside a hospital use the hand sanitizers at every opportunity and try not to breathe.
