The No Safety No Work campaign have put up 1000 of their previous stickers and decided to produce more with a range of slogans to fit the current situation. There are 4 designs, all A6 size with a QR code.
Other slogans are:
Support Health and Care Workers Big Pay Rise Now!
No Safety? No Work! Furlough for All!
NSNW will send them out for free, but please donate it you can to their crowdfunder: https://www.crowdfunder.co.uk/no-safety-no-work-campaign
