I work for a contractual research organization, and my lab specifically deals with trace metals analyses using ICP-MS, ICP-OES and AAS instruments, and I'm a fresher.
Even though I unquestionably understand and know things (this has been told to me not just by the seniors from my own department, but even managers from other departments feel this way and have told my fellow colleagues so), only my manager doesn't want me to be working on the machines even after having being in the laboratory for over three months now.. The "analyst qualification" (only after which can I be using the instruments and doing analyses) seems to be getting delayed even though he'd promised me to be ensuring it be done right after 45 days (company policy for minimum time to be taken for the same). I have asked him if I lack knowledge in any sense of the word, to please let me know so that I can learn and then go for the analyst qualification, but he has been unable to stop me on that front. He keeps saying things like "wait, it will happen" or "some things are not under our control" or "there are no samples". The last one especially irks me because I witness analyses happening every day.
Thereafter, he's told me that my "primary work" is to simply scan data documents that analysts are generating. More often than not, he asks me to stay after office hours saying that a senior is now preparing the documents (it's all handwritten, apart from primary machine generated data) and that I need to scan the documents and then leave. This takes a couple of hours, so I'm having to just literally loiter around in the laboratory while some senior is preparing the document, till they're done, then scan the papers and then leave. The women, however, are only given tasks that let them stay till the clock runs.
We have no overtime pay. This is a major reason why I don't like staying after-hours. Coupled with that, my current salary is just enough for basic survival, i.e. Being able to share a room with 3 others. Not an apartment, a room.
I have tried utilizing this time by asking my manager to teach me something but he just never does it. He'd pretend to be busy reading documents that are of no immediate use while I ask, and shortly after, get up and chat with other colleagues.
How do I handle this situation?
I'm considering going to my senior manager and seeking his advice on what I should do in such situations but I'm afraid it might backfire.
Oh, I'm also on probation and it'd last for six months. The company has never fired an employee, even when they're committing mistakes that render instruments useless for over a week.
Sending emails is not an option for me either.. The company doesn't issue emails to employees lower than managerial level.
