First, being ripped doesn't mean you lose money, it means you lose your vacation days. Vacation is assigned to you typically in blocks for 5 days, and members with 5.5 years or more of service get 26 days of vacation (5 weeks).
Being ripped means you work the days you would have had off. In the end there is no real loss to pay. That being said, getting a 45 day rip essentially means you don't take vacation for 24 months, and the only days you have off are your RDOs(regular days off, they rotate throughout the year due to the nature of shift work.)
Not being able to decompress for more than 2 days at a time is horrible in general and especially true in law enforcement, and I bet some members would rather lose thousands of dollars in pay in the form of a fine than not be able to take vacation for 2 years straight. This is not an option, you must lose the vacation days.
Did knowingly associate with a person or organization reasonably believed to be engaged in, likely to engage in, or to have engaged in criminal activities.
While on sick report, was wrongfully and without just cause absent from said residence without the permission of said officer's district surgeon and/or health services division sick desk supervisor.
While on sick report, left the confines of the city and residence counties without approval of the deputy commissioner of personnel.
Having changed her residence, did fail and neglect to notify her commanding officer by submitting form change of name, residence or social condition.
Did fail and neglect to notify the department of criminal activity committed by a person known to the department.
While on-duty, did wrongfully conduct personal business while on duty.
While on-duty, did fail and neglect to maintain activity log.
Essentially what this is, is a cop that was associating with a known criminal, but didn't necessarily do anything illegal. The department was looking for something to "get" them on, and how they "got" them was by following them home.
When you call in sick in the NYPD, you report to a department doctor (district surgeon) and then you must be in your primary residence (that the NYPD was informed of) during the time of your normal shift. From time to time, they send people around to check to see if you're home. They most likely sent someone to check on this cop hoping/knowing they wouldn't be there.
It turns out that this cop was in another location, which was reported to the NYPD as their primary residence.
Many of the citations in their record deal with being punished for lying about where they live.
"Personal business" could be anything not related to your job. For instance: they got you on a recording calling a friend on duty.
"fail and neglect to maintain activity log" most likely means that the NYPD confiscated all of their memo books (you're required to keep every single one you've used from the moment you report to the police academy to the moment you retire. Cops accrue dozens and dozens over a typical career. Almost no one has perfect memo books, and this rule is selectively enforced to punish people when they can't find anything else.
To summarize: This police officer was associating with someone the NYPD didn't want them associating with, and after investigation, held them accountable in the form of not being able to take vacation for 2 years because they were living at a different address than they reported, conducted personal business on duty, and did not have perfect memo books filled out to exacting standards over the course of their career.
It's very likely that the person they were associating with was a real problem, and that is why they got such a relatively heavy punishment. There's no way to know for sure, those secrets remain secret forever.
You may ask, Why are there so many convoluted rules regarding the minute to minute lives of the NYPD? and the answer is over 175 years of tradition and the collective bargaining agreement.
