Is it 75% of laboratory workers or 75% of all staff? I imagine clerical/administrative/IT/support workers can easily work from home.Also realistically how can lab workers work from home? 75% is a huge number...
Is it the same 75% of people always working from home or is it rotating, with 25% working on Monday then a different 25% working on Tuesday? (e.g. do lab work 2 days a week and paperwork 3 days a week)?
Since this is obviously something you've researched yourself and totally not something you've cut and pasted from an antivax site, these should be easy questions for you to answer.
