Lack of communication between the manager, supervisor and helpdesk causes that you are sometimes lost in what you have to do.
Do not think, just follow the instructions blindly, you pay for it.
A lot of unplanned overtime and unexpected work on weekends. I do not mind overtime, but if you find out about it on Friday after 3:00 PM it's not cool anymore.
In the beginning, the work brought a lot of satisfaction and pleasure, but after one year I changed my mind.
Long hours, miscommunication, no brakes.
