A little back story,
I've been with this company for almost 3 years. Not once have I gotten a raise. I've gotten high marks on all my performance reviews, but since “it's not in the budget” I haven't gotten a raise. I rarely took any days off the last 3 years, rarely called in, and have accumulated a total of over 150hrs of comp time, sick time, and admin time for me to use freely. They're only paying me out my vacation. The rest of the 150hrs I have, I either use it or lose it.
For the last 6 months, I've been applying/sending out resumes to get a higher paying postition. I finally landed a new position. I submitted my 2 weeks notice and decided to burn my earned time. I got a call telling me “I'm not allowed” to use my time and wanted me back in the office. I politely declined coming to the office and have time to burn and will most likely lose 70+hrs if I take off the 2 weeks.
Do yourselves a favor and if you have time to burn, use them. Don't end up like me where all your earned time goes to waste and unpaid.
