Learn Turkish: Üretim başlayınca fabrika çok işçi alıyor. - When production starts, the factory hires many workers.

It comes from the verb root başla (to start). Because this root ends in a vowel, we add the buffer letter -y- before attaching the -ınca ending. This creates başlayınca, meaning "when it starts".

Can başlayınca also mean "as soon as it starts"?

Yes! The -ınca suffix can translate to either "when" or "as soon as". It shows that the second action (hiring) happens right after or directly because of the first action (starting).

The translation says "many workers". Why doesn't işçi have the plural ending -ler?

In Turkish, whenever you use a quantity word like çok (many/a lot) or a number, the noun that follows it must remain singular. Therefore, it is correct to say çok işçi and incorrect to add a plural suffix here.

If alıyor comes from almak (to take), why is it translated as "hires"?

While almak literally means "to take", the phrase işçi almak (to take a worker) is the standard Turkish way to say "to hire". It is very similar to how an English company might "take on" new staff.
