1. This will not effect directly, but the employer might initiate disciplinary inquiry upon you by serving a show cause notice.
2. Trial will take 3-4 years.
3. If you are found guilty then also after initiating a disciplinary inquiry the employer might terminate you, however there must be a clause to this effect in your service rules.
4. This can not be told beforehand, depends on the trial.
5. You will not be eligible for the government job if you are convicted by the court.
There will be no issue with the job till the case is pending.
If you feel that the FIR has been lodged on false, frivolous and vexatious grounds then you may certainly go for filing a FIR quashing petition in the High Court.
