A friend worked as a handyman/caretaker in a care home. He's been there about 18 months and expressed several concerns on H&S issues. The last straw came when he was asked to do some electrical work, which requires a qualified electrician. He's not en electrician, has never claimed to be and was not employed as such. He refused to do the work and was sacked.
As I understand it, as he hasn't been there 2 years they can sack him for any or no reason, but I seem to remember there is some redress if it's a health and safety issue?
