HR is trying to circumvent legality at every turn: booking vacations on non legal notice, giving incorrect information about bank holiday legislation, providing fuzzy details about promotions. On top of overall terrible organization, long reply time and lack of empathy and common sense.
Salary is not good and you are not remunerated by your skill level but by your seniority. Zero incentive to be competent since incompetent people are paid the same as you. Difficult work is, however, pushed to competent people while the rest do the bare minimum to get paid.
Mentality of call center, even though no one in the project takes calls (scheduled and timed brakes, random SLAs that make no sense for the kind of work you are doing, on site work, etc)
