In the UK the probation period is effectively meaningless. Until you’ve been with an employer for 2 years, you don’t have any rights to an employment tribunal, except when the dismissal is “automatically unfair” (eg discrimination due to sex, race, disability etc).
And I bet it’s usually hard to prove that was the actual cause unless the employer was stupid enough to say it.
Yeah I know someone who used to do employment tribunals. She says it’s a ridiculously high standard and most employers are not that dumb. She’d only really take cases where they haven’t paid their wages and the employer was a mess. The amount of pregnant women that would come to her and she just couldn’t help.
