guys first time replying to a thread here

currently my team members are all quitting 1 by 1 which makes me very stressed out because they are what keeps me going at work. some new joiners quit before 1 month even. can't blame them because of the culture here, management keeps overloading us with last min request, everything all urgent urgent. anything also is our fault even though we are doing our best, OT everyday. the truth is there is not enough manpower but management keeps saying they cannot increase headcount. I know for sure if I stay on I will go ccrazy. should I start finding a new job? or try tahan.
