Believe it or not being slightly late is commonly used to fire union employees in the US as well. Usually the union and business come to an agreement on such policies. These are then enforced with no exceptions. Even for 20 year employees. There is zero flexibility or nuance for special situations. If your employer does not like you in the US they will do petty things like fire you for being 1 minute late. The best the union can do is make it so you have to be 1 minute late several times before you are canned.
