You can work cash in hand but it’s up to you to claim your own taxes.

I worked a cash job(warehouse) eight years back for a year and half and the first three months I didn’t claim to help me get back on track to get a new apartment faster than after I did claim did taxes never came back to haunt me. I know so many people who don’t claim tips and only claim taxes on their bartending jobs and no clue to this day how the government isn’t like we know you can’t survive on less than minimum wage and look into it (Canada)
