Micromanagement,Culture is Dying,Very Poor Hike

CEO approval
Business Outlook

Pros

Remote work is still allowed to employees.

Cons

Blueplanet Inventory(convergence) is full of micromanagement.Managers ping multiple times even if the work is on track. Whole year was filled with extra extended working hours but managers didn’t allowed to fill extra time in timesheets. Too much work and zero appreciation and rewards. Minimal hikes of 5-7% even when company is in profits and shares are all time high.
