I had a situation jus like this last year in mid september.
I damaged my big toenail on my rite foot when my stupid site manager asked me to help a colleague to carry a hevy plastic storage unit. the thing was falling to pieces as it was not assembled properly so 1 piece fell on my toe and it bloody well hurt. so went home but struggled 2 com back 2 work on following monday i was limping my toenail was bleeding painful and black after dat i was on sick for 6 weeks. i told them i was going to be off 4 a few days or maybe a week or so but wat happens i got classed as awol cause i didn't keep regular contact wit them & they knew y i was off but wanted 2 make an issue out of it. i got a warning 4 it and sick pay was witheld even though i supplied back dated sick notes. also i coldn't sue the fukkers cause i was told i was wearing inappropriate footwear & wasn't following uniform policy every one in my work place don't wear shoes.
i think we still liv in the dark ages here no workers rites any more.
