したら and したあとで - different or same


> 仕事終わったら飲みに行く。

> 仕事終わったあとで飲みに行く。

Is there any difference between these three sentences?

Does it work the same as in [this
question](https://japanese.stackexchange.com/questions/40787/difference-
between-%E3%81%A6%E3%81%8B%E3%82%89-and-%E3%81%9F%E3%81%82%E3%81%A8%E3%81%A7)?

> 仕事終わってから飲みに行く。



[code]

    仕事終わったら飲みに行く
    
[/code]

Focus on the conditional aspect of `when/if`. Being `仕事終わる` a true sentence,
then B `飲みに行く`.

[code]

    仕事終わってから飲みに行く
    
[/code]

Indicates a short time span after `仕事終わる`. The first thing that happens after
A is B.

[code]

    仕事終わったあとで飲みに行く
    
[/code]

Indicates a larger time span. You finish work, but not necessarily you go
drinking after it. You might stop by at home, for example. That is why
sentences like `離婚した後で`、付き合うことが難しくなってきました don't make sense if you change to
`離婚してから`.

[code]

    仕事あとで飲みにいくに
    
[/code]

Is wrong. The correct way is `仕事の後で` or `仕事後に` using 後 as a suffix with the
reading ご. This pattern is equivalent to `仕事終わったあとで飲みに行く`.
