Recently I have read one of the stories from Humans of New York and I came across such sentence:
she fully understood how things work here. She was a news reporter back in the Bahamas. But the only job she could get here was taking care of old people. My dad could only work construction.

I got interested why there is no preposition after work. I have always thought it is to work in construction/education/finance.
On the English Stack Exchange forum I only found posts connected to different prepositions following work but there were no threads about work standing alone before the name of a job. I couldn’t find any other examples of this kind on the Internet; they were all containing prepositions or the word order was switched into construction work. I’m not sure whether it’s legitimate usage or more slang-ish way of saying My dad could only work in construction jobs.
