Not only use up your vacation time ... but also your sick time, volunteer hours (24) and any other hours you may be entitled to. I'm not trusting that the company will pay out vacation time (I do not have unlimited PTO as some have stated) and will be front-loading my vacation and personal time off.
I keep a close eye on where my sick time is too and use it immediately once it hits 4 or 8 hours so not to lose it. Calling it a "mental break" from all of Nielsen's toxicity. It's a shame as I've never had to really use sick time, maybe once or twice a year if that. Now it's a monthly must have to keep the stress in check, and I'm not leaving any time on the table.
