Should I look for a new job?

So currently I use to get 70 hours every 2 weeks but it has been super slow so my manager is cutting my hours I talked to him about yesterday and he told me the days he scheduled me off I could come in

He gave me 4 DAYS off that’s horrible and the other insiders he doesn’t even schedule he just leave them off the schedule so i just don’t come and not ask so I texted him today and asked if I could work tomorrow and he isn’t responding at all should i just look for a new job ?

This place is so stressful but I make good money here but he’s cutting my hours which is surprising .
