In most banks, freshers emp. ID are used by other senior staff whenever they require details of people they are concerned about. India is a joke to privacy and here people think it's their right to use other people credentials to access details of others.
Whenever a new female staff joins and they have less experience of technical knowhows they are easy target for those employees having malafide intentions. Same happens in IT companies.
When I joined TCS in early days, a senior engineer their tried to access my account but on Day 1 itself I changed my password and asked him why he needs it. Whenever I logged in I hide keyboard with paper so that even in cameras they won't be anle to see it. Checked whole system to see if any key logging or password logging files are there. There wasn't. Actually It's none of his business to have my credentials for their own malafide intentions.
Same happened in INFY but I never let people get control over me. Lived like a lion and kept people in their place no matter how much they threatened me and others. You should always know the rules and threaten them back with that.
Being a senior I never tried to use my junior team. Instead made them feel good and grow/develop in life. But kuch log mc hotey hai aur unka ilaaz karna padta hai chahe aapko job ko laat maarni pade.
Stay one step ahead of what others are thinking or can do.
