On the 30th of January the Bayer Crop Science facility in North Newbalds, North Yorkshire had all its locks jammed with metal and superglue.
This is the 3rd or 4th time this has happened at this building.
The jamming of locks is a quick and simple action which can be carried out very safely at pretty much any Bayer location in the country. It can also have an effect disproportional to the effort put into it - when workers are unable to get to work productivity will surely suffer.
