Another big company is requiring 4 days in the office. Also from May. I am just curious if I will be fired coming only 3 days a week. Worst case I will commute by train and will login to the system in the train to clock in my 8 hours daily. Having commute time added to work time is acceptable to me. Still hate cheap open space office and will look for another job when the layoffs are over.
