First things first, in English we do not talk about half-time jobs. Half-time is the break in a football match and a ‘half-time job’ would be to bring on the oranges for the players!
If you’re not working full-time, you’re probably working part-time.
The other mistake in the example concerns the word ‘fabric’. In English, it is not a place of mass production, it is another word for cloth or material for things like clothes and curtains.
The big place of work is called a factory. Some factories produce or deal in fabric – but the two are completely different things.
