Loyalty is demanded by employers from employees, especially when unpaid overtimes are demanded. However when it's employers turn to reciprocally show loyalty to the employees it usually doesn't work. You aren't getting bonuses for your last year's unpaid overtimes when the company starts getting profit from your job. You need to beg for unpaid time off when you need to do anything at your home despite working many unpaid overtimes. You aren't getting salary rise for your hard work. You are being treated as disloyal replaceable resource. You need to be on a job hunt constantly.
