Shocks widout Warnings!!

I've been working with ICICI since 2008 everythg was fine I had mny promotions wid a promotion too in the last FY of my recent working tenure..n then all of a sudden before few days of COVID, our profile staff received a mail that they going to end the whole profile from the very next day...the question is now how our profile staff going to make it thru when our profile was ended in a day and bank wud not b doing much, rather then depending on the people already there in other departments higher profiles to adjust us into the system somewhr....n as we all was handling audit profile so sumtimes we had to be a bit strict for getting the staff asking them to follow the process..making them do additional stuff was always taken as a burden so but obvious due to which we r no one's fav either..tht never liked us much..hence the implications was no departments head wanted us to become a part of the teams that to from a operations profile in a bank full of sales targets in every department it was a big no no..finally after taking all the measures to save our jobs when nothing worked out .. one fine day i received a call from HR tht either u leave the job by your own or we have to fire you (it was sugary quoted but obvious) inconveniently i had to leave the job.. without a backup job..after 13 plus years of work ex..i feel cheated as after receiving the bestest rating and a promotion in the previous recent year of my tenure with all my hardwork n a travelling job, as a single parent, staying away from my four year kid at home leaving him wid my parents ..just bcoz the profile was finished i was all of sudden not of any use n 'no one' to the ICICI Bank..overall this is the culture of many companies asking the employees last minute to leave..the more I love n felt proud working for 'MY' ICICI Bank the more betrayed i felt when i had to leave it abruptly..thts y PPL say "Love your job, not the Company" . A learning I took back home pretty late.
