Oh boy...............
You may be unfairly dismissed but this is a matter for civil courts/tribunals to decide not the HSE.
SOTV - this exactly my point! I used the HSE as an example as to what employers have to deal with! It isnt simply a case of playing Donald Trump! Again, my personal opinion or yours isnt what at issue here, it is what employers have to deal with to avoid exactly that: unfair dismissal.
If an employee claims he/she is an alcoholic due to stresses at work etc (again might be a lie but is irrelevant) then an employer will undertake a different course of action than dismissal, they will offer councelling, different place of work etc etc Anything to make sure that at the end of the road they do not get unfair dismissal thrown in their face!
