- You have to migrate a lot within company to get better salary
- You will probably never be recognized inside of operation team, even if you have outstanding performance in comparison to your colleagues
- Hundreds of people in this company do absolutely nothing and the job positions are artificially created and maintained for no apparent reason, which leads to other employees to loose motivation
- It feels like manager / production employee ration in this company is 1:1, for no apparent reason, if you really need managerial help there are very few people (good managers) to support you
- Processes will stand in your way on daily basis
- Never-ending rescheduling of maintenance windows, it happened to me that I have to wait one year to get some basic maintenance done, only due to processes
- Biggest disadvantages are bureaucracy and that always the most skillfull people in each team have to carry all the production altogether with the process employees to keep this company running, out of 4000 employees maybe 500 do the real work, which is very sad but true
- Managers expect people to do extra work, they expect production to work on automation and so on, but invest nothing in it. There is no salary reward and they always buy the cheapest machines, the cheapest vendor.
- Only real goal for top management in T-Systems is profit, but they won't ever say it openly and will try brainwash you to worship "4 pillars" and to motivate you to work more for the same salary for years
