"Hledejte lepší zaměstnání."

[IngridLind18]

zaměstnání could be employment as well as job, couldn't it?

[kacenka9]

yes. Though employment is uncoutable

[danda.panda]

Employment is both uncountable and countable. Uncountable is used way more often in everyday conversation in the meaning of general employment, but countable does exist as a synonym to job, e.g. "List your previous employments."

[EinatAdar]

Look for a better employment was suggested, but when I tried to use it, I got an error.
I'm not sure if it's correct or not, but it shouldn't be suggested if it's wrong.

[Renardo11]

Think of the “suggestions” more or less as of a dictionary. Not every translation for a single word is appropriate in every context.

If you think “employment” should be an accepted translation I suggest you ⚑Report it.
