Bangalore Startup work culture is becoming toxic

Hi All, I think with funding winter, the work culture in Bangalore Startups is becoming toxic day by day. In my company, it started with filling the daily time sheet of what work we did, then why do we need work from home( Company gives 4wfh/month), then a circular came today that every data filled in timesheet will be minutely checked with card punches, can't be late even for 5 minutes more than 3 times a month. The hypocrisy part is employees are underpaid(5-6 LPA for software developer) and overworked(9+ hrs/day). I got to know one more startup where they have normalised 12hrs/day 6 days a week working and if you work less, it will affect negatively. They force their employees to reside nearby to the office so they can work till 12-2am from 10.30am. Is it common everywhere?
