Come on, the myth that it's hard to fire incompetent people is total bullcrap, perpetuated by executives to avoid dealing with unions. I live in one of the countries with the strongest union protections and traditions in the world. It's not hard here to fire someone if you want to fire them´, even if in union.

I live in Australia and it's an absolute pain in the arse to fire someone for performance issues, assuming they work at a medium or large business (e.g. of more than 20 people) and they've made it through their 3-month trial period. You have to PIP them and the process takes months.

I've known of two engineers whose managers told me they would have fired them, but higher management wouldn't let them initiate the PIP process. The one case where I worked at the company was pretty bad. We had to shuffle the individual off onto makework jobs where they couldn't do much harm.

I don't think it's fair to blame this entirely on unions when it's the result of big businesses being too scared to follow a process that was given to them by the government. Unions mostly fight real unfair dismissals and only play a minor role in creating a chilling effect. Still, in practice it's hard to fire someone.
